Hi, My data has column names which has ` character. For example , *> names(dataframe) [1] "`region" "farmsize`" "farmincome" "maincrop" "claimvalue"* If i use these objects in my function, the following error is thrown. *lmm<-lm(``region`~farmincome) Error: attempt to use zero-length variable name* Is there a way, say an escape sequence or something similar in which we can give these objects with the colnames to R functions?
The mathod used inread.table is to call make.names()
make.names(x)
[1] "X.region" "farmsize." [3] "farmincome" "maincrop" [5] "claimvalue" -- David Winsemius, MD Alameda, CA, USA
