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? Thanks in advance. Regards, Raji -- View this message in context: http://r.789695.n4.nabble.com/Column-names-containing-in-R-tp4648553.html Sent from the R help mailing list archive at Nabble.com.
Column names containing ` in R
3 messages · Raji, Rui Barradas, David Winsemius
Hello,
Can't you remove the backquotes from names(df)? If so, you can do it with
x <- c("`region", "farmsize`", "farmincome", "maincrop", "claimvalue")
newx <- gsub("\\`", "", x)
Hope this helps,
Rui Barradas

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
