Sum two variables

For whatever reason, if you sum two variables var1 and var2 from df, you might get the following error: Non-numeric argument to binary operator.

To circumvent it, just be sure that both variables are numeric within the sum:

df$var3 <- as.numeric(as.character(df$var1)) + as.numeric(as.character(df$var2))

By “within the sum”, I mean you need to write this in one single line. If you break it in two or three lines, it won’t work ¯\_(ツ)_/¯
