aes_string() is deprecated — replace with tidy eval aes() in plot_wrapper.R

[konradbuessow]

Hello Swarchal,

aes_string() was deprecated in ggplot2 3.0.0 and now triggers deprecation warnings on every plot.

All occurrences are in R/plot_wrapper.R, used identically in plt6, plt12, plt24, plt48, plt96, plt384, and plt1536.

Possible fix: replace aes_string(x = "Column", y = "Row") with aes(x = .data[["Column"]], y = .data[["Row"]]) (and similarly for the Var1/Var2/values calls).

Best Regards,
Konrad
