similar to: RODBC: data base with decimal point ","

Dear R-users, I am working with R version 2.10.1 and package RODBC Version: 1.3-2 under windows. Say I have a table "testtable" (in an Access data base), which has many different columns, among them a character column "X" with "integer-like" data as "0012345". Using sqlFetch, I'd like to assure that column X is read in as a character variable. So what

Dear All! Reading character strings containing an "umlaut" from a csv-file I find a (to me) surprising behaviour in R 2.8.0, that I did not notice in R 2.7.2. A comparison by "==" results in FALSE, while grep does find the aggreement. See the example below. The crucial line is x=="div 1-2 Ver?nderungen", with the result [1] FALSE in R 2.8.0 but [1] TRUE in R

hi, i'd like to install the package "RGoogleDocs ". i downloaded to path "E:/R/R-2.13.0/library/RCurl_0.91-0.tar.gz" i run R from an usb-stick and can't get the install.packages() prompt to run correctly - can anyone help with this? thanks, kay > sessionInfo() R version 2.13.0 (2011-04-13) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1]

All: I am using RSqlite and want to be able to update individual values in a record, such as with this simple example: library(RSQLite) drv<-dbDriver("SQLite") con<-dbConnect(drv,"test.db") my.data<-data.frame(countries=c("US","UK","Canada","Australia","NewZealand"),vals=c(52,36,74,10,98))

Dear All, Encoding() goes beyond my understanding. See the example. I would expect from reading the help for Encoding() that strsplit preserves the encoding for each resulting element, but for simple letters it gets lost. Also it seems that an Encoding() cannot be declared for simple letters. They remain in any case "unknown". In paste() "latin1" seems to dominate

Dear All! If I try to compare the attributes of two objects, I find a surprising behaviour of attr.all.equal(). With identical attributes I receive the answert NULL. If the attributes differ, the answer is as expecxted and differences are shown. all.equal(attributes(), attributes()) instead returns TRUE, if attributes are equal. See example: v <- 1:5 attr(v, 'testattribute')

Dear All, trying to write a data.frame, containing Surv objects to a csv-file I get "Error in dimnames(X) <- list(dn[[1L]], unlist(collabs, use.names = FALSE)) : length of 'dimnames' [2] not equal to array extent". See example below. May be, I overlooked something, but I expected that also data.frames containing Surv objects may be written to csv files. Is there a

Many thanks Bert, now is ok, i did not know that "Namensraum" should mean a package Am So., 16.

So update the vctrs package to the latest version first before loading R-tools (or the caret package, specifically)? -- Bert On Sun, Apr 16, 2023 at 1:57?PM G?bor Malomsoki <gmalomsoki1980 at gmail.com> wrote: > > I have newly installed R, R-tools, RStudio, but still not working: > > library(caret)Lade n?tiges Paket: latticeError: Laden von Paket oder > Namensraum f?r

Dear all, my aim is to integrate R in an interactive visualisation software called Bulk Analyzer developed by VrVis (http://www.vrvis.at). the code: SEXP e, tmp; ParseStatus status; PROTECT(tmp = mkString("x <- c(1.234,-3.45)")); PrintValue(tmp); PROTECT(e = R_ParseVector(tmp, -1, &status, R_NilValue)); PrintValue(e); UNPROTECT(2); produces the following output: [1] "x

This is my first attempt at this, so hopefully a few kind pointers can get me going in the right direction... I have a large data frame of 20+ columns and 20,000 rows. I'd like to evaluate the distribution of values in each row, to determine whether they meet the criteria of a normal distribution. I'd loop this over all the rows in the data frame, and output the summary results to a new

Hi UserRs, I know that there has to be an easy way to do this in R (probably easy enough that once someone clues me in I'll smack myself on the forehead for not figuring it out myself), but my searches on my own have not yielded any hints. I have many fields in my dataset that participants entered as "free lists" - i.e., the field constitutes a varying number of names each

Hi all; I have a custom iproute2 table and a few rules to go along with it (CentOS 5) -- I have added the table to /etc/iproute2/rt_tables. if-up and friends doesn't seem to handle this real gracefully. How are those of you out there doing something similar managing this customization? I don't really want to muck with /etc/init.d/network or the if-up scripts to avoid breaking upgrades.

Dear All, to drop unused factor levels two ways are outlined in R-help. In both cases a label attribute is lost. The same happens, when using car:::recode. Is there a simple way to avoid losing attributes? Thanks, Heinz ## example ff <- factor(substring("statistics", 1:10, 1:10), levels=letters) attributes(ff)$label <- 'test label' attributes(ff)$label gg <- ff[,

Hi, I hope you guys can help me, I already posted this question on stackoverflow but did not get any help (which worked). And I need to solve this problem as quick as possible: In our firm we migrated to windows 7 (64-bit) and also updated the java packages (1.6.0_24) and also R (to 2.15). Then I tried to install my packages which i use daily and one of em is the xlsx package. But if I load the
