Some of the countries look a bit distorted such as Spain and Iceland. You might play with the projection type by changing the "crs" (coordinate reference system).
Thank you for this video! How would you go about keeping the records of NA values to still have the country showing on the map but blank on the inside so it does not influence the color scale of the legend?
Hi, this tutorial is really good and easy to follow, I have created the same map, But I'm having difficulty adding scale_bar or annotation_scale, Could you please show this to viewer how they can add these scales.
I love your tutorial, it was quite helpful when I was trying to do a map. Is it possible to add countries to the map with a value of 0?, maybe not in the gradient, but afterward just add a country? That would be very helpful to me.
its not showing Democratic Republic of Congo and Congo Kinshasa, any reason, maybe input names are different. United States will only load when wriiten as USA. thanks for a great workshop
Hi! Very informative tutorial - if we want to rather have a different colour for each country (not based on any number data), R will automatically assign some colours - how do we change them?
For filtering the map down to EU countries only when i use the code - mapdata1% filter(!is.na(mapdata$`All antibiotics`)) View(mapdata1) ``` i get an error message: Error in UseMethod("filter") : no applicable method for 'filter' applied to an object of class "c('gg', 'ggplot')" -- any help with this?? thank you
Thanks for this video! I had created my first map of the world. For some reason I have a missing gap of South Africa missing while the rest of the countries are present. Is there something wrong with my dataset?
Amazing video, super helpful! Question, on line 17 of the code where you go to filter the mapdata, what does %>% do ? My R does not recognize it as a function and won't let me filter it with that
It's from tidyverse and is called a pipe style.tidyverse.org/pipes.html it just executes operations taking an input and giving an output. Install tidyverse and it should work!
Thank you for uploading a wonderful tutorial. I have a query that how we can plot two variables data on single map. Like : ggplot() + geom_sf(data=shape, color='grey20', size=0.1, fill=NA) + geom_sf(data = subset(clus_dzc1, type=='high'),aes(fill=CL2),size=0.1,color='black') + scale_fill_discrete_sequential(palette='Burg',name="High-risk",rev=FALSE, guide = guide_legend(ncol=2)) + theme_void() ggplot() + geom_sf(data=shape, color='grey20', size=0.1, fill=NA) + geom_sf(data = subset(clus_dzc1, type=='low'),aes(fill=CL2), size=0.1, color='black') + scale_fill_discrete_sequential(palette='Blues',name="Low-risk",rev=FALSE, guide = guide_legend(ncol=2)) + theme_void() . There are two plots code. Can you please guide me, how i can convert into one gg plot. Can you please write the code for me. I shall be very thankful to you.
What can you do when their is not a mutual variable between the map data and my own dataset ('region' was the example given here). My countries are also coded indifferently to map data, will these cause some issues? Any help would be very much appreciated for my dissertation! (I'm very new to R)
What is the best way to get the map data 1? I've watched every video on UA-cam from beginning to end, but I'm still unable to locate the vaccination percentage map. Is there a solution?
Hi! Great video! But I always get the notification "Error in left_join(mapdata, fieldworkplaces, by = "region") : could not find function "left_join"". Any ideas on how to solve this? Thanks!
So I have a dataset with volcano names as well as their own longitudes and latitudes. Is there any way I can plot that data into a map that shows their locations as points using this method?
I have just ran all the code and it all works fine, I imagine that you have a slight mismatch between what you have called the object and what you are asking to View() Here are all the cases were there is an object defined + a view in the script that's linked below the video EUvax
@@DrPC_statistics_guides, It's a great video. I am trying to plot it, but from where I may get the mapdata? I am finding "Error: object 'map1' not found".
Simple, clear, to the point and very easy to follow at the same time. Thank you for this nice work.
Thank you
Best explanation of mapping in R I have found till now and I have been researching a lot!
Thank you!
Your tutorial helped me a lot in plotting my data. Thanks.
It's a clear and straigthforward explanation. Thanks.
Thanks. Although instead of a left join and then filtering you would probably get the same result with a right join
Cool tutorial, thanks! I'm just getting into R and I found this to be very helpful.
Edit: Give my regards to Bill too.

Thanks!, Really helpful better than my textbook!!
Nice demo of ggplot plotting maps.
There is a short-cut for eliminating NAs - namely: drop_na(Perc_vaccinated).
fabulous! what do you do if you do not have and equivalent value in your dataset for region (or any other)? instead, one might have "area" or "code"

Hello, Im just trying to put data lebel on the region. But i cant do it. Tried a lot. Can you tell me how to do it?

Super helpful video! Would it be possible to add the NA value to a separate legend to say that NA = grey on your map? :)
hi, how to solve the problem of incompatible types when i do left_join function? thanks
Nice video and I was looking for this type of material to plot my data. I will try and soon and hopeful that I can replicate the same.
Any reason "united States" is missing when creating mapdata?
Amazing video, super helpful! Do you have a video yet on how to animate it? I have data from 2005 to 2020 and would love to animate this map?
Not yet, gganimate package will do it for you, I will get around to making an animation video soon!
Great video. Thank you.

yes, all countries can be done, I limited them to the ones I had vaccination data for.

Try,

them_void in base ggplot2 removes all the axis stuff for you so you don't have to write it out
