I am reading a list of numbers from my clipboard, and have been successful, except I can't make a histogram as R doesn't recognize my variable as numeric. I know I need to use "as.is", but the specifics escape me.
I have used x<-read.table("clipboard", header=F) to import from a txt file. How do make this numeric? Thanks, J.
So the elements of your data frame "x" are not numeric? read.table() auto-detects which variables are numeric or not, so there's something strange with your textfile, I guess.
as.numeric(x$V1) converts the first element in your data.frame x to numeric.
