Hi R user, I wanted to change a column name with new one but it comes with "." where there was space. Is there any way to keep my formate with space? Here what I foundImages<-stack(imageA,imageB,imageC) names(Images)[3]<-c("dif of AB") head(Images) It gives the column name of 3 as a "dif.of.AB", but I wanted to be "dif of AB" I don't want to put the "." on the spaces. Any suggestions?
(1) Forget about what you "don't want" and leave the dots be. Spaces in variable/column names are an abomination, tolerated only by the great unwashed (i.e. users of Windoze).
(2) See fortune(37). (3) It doesn't happen to me: set.seed(42) Images <- data.frame(x=rnorm(1),y=rnorm(10),z=rnorm(10)) names(Images)[3] <- "dif of AB" names(Images)
[1] "x" "y" "dif of AB"
There may be some setting that enforces "syntactically valid" names, but I see no such setting associated with names(). (There *is* such a setting associated with data.frame() --- are you telling the truth about how you formed the new names of "Images"?)
