Re: [R] generating factors from the edit function

Hi Erin, I am assuming this is for pedagogical purposes (i.e., make R less intimidating by not reading data in). If that is true, you may just want to automate the whole process. I am typically twitchy about using assign(), but fix does it and again if only for introducing students to R. ##

Re: [R] generating factors from the edit function

Here is a little function that I put together: > fact1 function(x) { n <- ncol(x) for(i in 1:n) { if(mode(x[,i])=="character")x[,i] <- factor(x[,i]) } return(x) } > It does the trick. I'm sure that there are better ways, but this seems ok. Thank you!!! Sincerely, Erin On Fri, Mar 4, 2011 at

Re: [R] generating factors from the edit function

Hi Erin, I would set up the data.frame the way you want it before calling fix(). Something like test2df <- data.frame(v1=numeric(), v2=factor()) test2df <- fix(test2df) Best, Ista On Sat, Mar 5, 2011 at 4:34 AM, Erin Hodgess wrote: > Dear R People: > > If I use the fix or edit function for a ne

[R] generating factors from the edit function

Dear R People: If I use the fix or edit function for a new data frame, I would like to have my character data as factors. Is there a "built in" way to do this, please? Here is what I did: > test2.df <- data.frame() > test2.df <- fix(test2.df,factor.mode="character") > str(test2.df) 'data.frame'
