I am finding complex analyses easier than some elementary operations in R. In particular I want to do some low level exploratory data analyses with data in a data frame but cannot find commands to easily insert, remove (delete), rename, and re-order (arbitrarily, not sort) columns. I see that the micEcon package has an insertCol command, but that is for matrices, not data frames. I have looked

Hello, colnames seems to be not optimized well for data.frame. It escapes processing for data.frame in if (is.data.frame(x) && do.NULL) return(names(x)) but only when do.NULL true. This makes huge difference when do.NULL false. Minimal edit to `colnames`: if (is.data.frame(x)) { nm <- names(x) if (do.NULL || !is.null(nm)) return(nm) else

Hello R users, For the last few days I am struggling with the following task: my data.frame: A1 A2 A3 B1 B2 B3 58.81 53.292 54.501 13.013 17.39 19.407 56.02 56.251 54.033 20.099 13.15 10.411 55.376 53.099 57.625 13.396 21.031 13.22 58.584 53.194 54.218 13.038 16.854 19.289 55.7 55.921 53.847 19.942 13.153 9.828 55.093 52.934

I am sorry to ask such question, but I can't find a solution... I have a dataframe 'd2004' and I want to remove two columns: 'd2004$concentration' and 'd2004$stade". I could do it just as follows: > names(d2004) [1] "Localite" "Date" "parcelle" "maille" "presence.plant"

Hi, Use Newdata <- subset(d2004, select=-c(concentration,stade)) See ?subset for details Best, Matthias > -----Urspr??ngliche Nachricht----- > Von: Jacques VESLOT [mailto:jacques.veslot at cirad.fr] > Gesendet: Donnerstag, 09.

Hello Roland/Louis & All, All the best for the new year. Sorry to bring this up again. I finally managed to give some more attention to this issue of mine. I've set up a new test domain server, and I managed to seamless migrate from SAMBA_INTERNAL to BIND9_DLZ and the other way again. With a little help of new software we purchased, I exported all data from production and imported the

Dear all! I have a data frame composed by 13 columns (year, and 12 months). I want to transform this data base in another like this year month values 1901 1 1901 2 1901 3 ..... 1901 12 1902 1 1902 2 .... 1902 12 Is there a possibility to succeed that in R? Thank you! best regards! CR -- --- Catalin-Constantin ROIBU Lecturer PhD, Forestry engineer Forestry Faculty of Suceava Str.

Dear R-help, I am having trouble with your scatterplot3d program. For help with this problem I was directed to your address by Martin Maechler at " r-core-bounces at r-project.org." I'm also sending a CC to " r-core-owner at r-project.org" as I'm not yet certain of the proper address to use for this. I have R version 2.8.1 and have downloaded 'scatterplot3d.'

Hi there, Any update on this? Should I create bugzilla ticket and submit patch?
