I have column names that contain brackets and spaces. I can import them using check.names = False.
However, after importing the subset function does not work anymore. I have tried the following codes
test <- subset (df$"model code" == graph)
test <- subset (df, "model code" == graph)
test <- subset (df
this is the error Error in subset.default(df$"model mode" == "graph") : argument "subset" is missing, with no default
**How can I use check.names is false but still use the operator $**model code' == graph)
