similar to: Import excel file

Hello, In our structure, users connect to a server (64GB of memory) where they launch R. How can I limit the amount of RAM that could use a user. The function memory.limit(size=...) can limit the amount of memory but I would like users can't change this option in R. Is it possible? Thank you. Cyril Hervy [[alternative HTML version deleted]]

Dear all, Good day! I have a problem in reading Excel files in R and appending them to each other. Suppose we have several Excel files in a directory with headers and want to use R to append them in a single file with an additional variable in the final file indicating from which files the data come from. As I have many Excel files and their sizes are very big I should write a loop in R to do

Hi Everybody In R, the XLConnect package can read and write named region to and from Excel. In order to read a named region with the readNamedRegion function you need to know it's name. You can check is a name exists with existsName, but you still have to know the name. Is there a way to actually get a list of the named regions in XLConnect sinilar to getRanges in the xlsx package. On that

Hi, I tried to read xlsx files by "XLConnect" packages, but the dates are one day earlier than it is supposed to be. I moved from California to Taiwan (Eastern Asia), and it worked well in California, but not in Taiwan. Even if I adjust my Mac time to California time zone, it gives the wrong dates. I don't know which part of the setting (in RStudio or in my Mac?) I should adjust.

Buenos días Creo la siguiente tabla: > tapply(hogares_larioja$DB090, list(HX060=hogares_larioja$HX060, HS190=hogares_larioja$HS190, HH040=hogares_larioja$HH040, HH050=hogares_larioja$HH050, HH081=hogares_larioja$HH081, HH091=hogares_larioja$HH091), sum) y el resultado quiero exportarlo a excel (este y otros que he realizado, claro) para publicarlos. ¿Cómo puedo hacerlo?. Gracias BB

Jim, I don't see how that link could be related to John's issue. Symptoms related to your link involve discrepancies of four years whereas John is seeing discrepancies of one day. John, I do not see any attached files. Regards On Sat, Sep 23, 2017 at 1:30 PM, Jim Lemon <drjimlemon at gmail.com> wrote: > Hi John, > It could be due to this: > >

Dear R Users, I have to read data from many excel spreadsheets, all which have some frustrating formatting (lots of titles, headers, etc.). I am trying to work directly from source data and the number of the spreadsheets I would have to go through make reformatting one by one a pain. I have found lots of ways to read excel files, but my question is whether there is a way to only read
