Re: [R] Warning when running R - can't install packages either

Hi Jakub, This is really a separate question. It is not really end-user related, and should be asked on the R-devel mailing list. Nonetheless, some answers below. On 05/13/2016 03:55 PM, Jakub Jirutka wrote: Hi, I’m maintainer of the R package in Alpine Linux. I read on multiple places

Re: [R] Warning when running R - can't install packages either

Hi, I’m maintainer of the R package in Alpine Linux. I read on multiple places that some packages needs R_HOME variable set to the location where is R installed, so I’ve added it to the system-wide profile. Is this correct, or a misinformation? What system dependencies does R need to compile

Re: [R] apply formula over columns by subset of rows in a dataframe (to get a new dataframe)

ave() encapsulates the split/lapply/unsplit stuff so transform(mydf, v1.mod = ave(v1, blocks, FUN=mynorm)) also gives what you got above. Bill Dunlap TIBCO Software wdunlap tibco.com On Fri, May 13, 2016 at 7:44 AM, Massimo Bressan < massimo.bres...@arpa.veneto.it> wrote: > yes, thanks > >

yes, thanks you pointed me in the right direction: split/unplist was the trick I completely left behind that possibility! here the final version mynorm <- function(x) {(x - min(x, na.rm=TRUE))/(max(x, na.rm=TRUE) - min(x, na.rm=TRUE))}

This doesn't answer your actual question, but isn't it better practice to use ISBLANK instead of ""? As for your actual question, a check of the parts of your command at the R prompt would probably reveal something interesting: > paste("IF(A2=", dQuote(""), ",", dQuote(""), ",1)", sep="") [1]
