[R] character count
Dear list,
I have a variable that consists of typed responses. I wish to compute
a variable equal to the number of characters in the original variable.
For example:
> x <- c("convert this to 32 because it has 32 characters", "this one has 22
> characters", "12 characters")
[Some magic function here]
> x
[1] 32 22 12
Any ideas?

Re: [R] character count
nchar (c("convert this to 47 because it has 47 characters", "this one has 26
characters", "13 characters"))

Re: [R] character count
Thanks to everyone who responded. This turns out to be amazingly easy.
To count characters including spaces:
nchar(x)
To count characters excluding spaces:
nchar(gsub(" *","",x))
Thanks!

The * is unnecessary.

Re: [R] character count
Hi Ista,
one way could be:
ncharacters<-unlist(lapply(x,function(x)nchar(gsub(' ','',x
ncharacters
