Hi, While combining the graphs, I get the error "non-numeric argument to binary operator" . please help.

Hmmm. Generically, the error means you are trying to do something that requires numeric vectors (etc) but you are using non-numeric vectors (etc.). I don't think that matters here. My guess is that the patchwork package is not loaded (`library(patchwork)`). I got the same error as you when I didn't first run `library(patchwork)`. So, double check that.
