similar to: How to write a Surv object to a csv-file?

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

Hello everyone, I am attempting to use the %in% operator with the ! to produce a NOT IN type of operation. Why does this not work? Suggestions? > data2[data1$char1 %in% c("string1","string2"),1]<-min(data1$x1) > data2[data1$char1 ! %in% c("string1","string2"),1]<-max(data1$x1)+1000 Error: unexpected '!' in "data2[data1$char1

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) with 3 columns and 1 row that looks like this: X Y Z 0012345 42 42,1 The columns are of these types: X - character, Y - Long Integer, Z - Decimal. I use RODBC to get these data into R: > library(RODBC) >

Dear List, I try to make a xyplot with different colors and symbols, I came this far: library(DAAG) xyplot(csoa~it|sex*agegp,data=tinting,groups=target,pch=list(1,2),auto.key=list(space = "right")) this produces a plot with different colors and symbols but unfortunately the legend does only follow the color scheme and not the different symbols. Any suggestions what to change? And

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')

HI Team, I am currently working on problem and stumped on "for" loop. Data: structure(list(Coutry = structure(c(3L, 3L, 3L, 3L, 2L, 2L, 1L, 1L), .Label = c("J", "M", "U"), class = "factor"), State = structure(c(1L, 1L, 4L, 2L, 5L, 5L, 3L, 6L), .Label = c("A", "C", "K", "O", "S",

I have a function that manipulates a list of numeric and character components of equal length and wants to return a data.frame. EG, f<-function() { a<-list(Int1=1:5,Char1=letters[1:5],Char2=letters[6:10]) b<-data.frame(a) } How can I get the columns Char1, Char2, (...CharN) returned coerced to character and not factor? It appears that I could coerce individual columns by

Hi all, there appears to be something strange with the plotting of tables of 1 dimension; if I attempt to make a plot of a table of characters with only 1 value I get an error (Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ). With more than one value I don't get errors, neither with integers (even if only 1 value): tbl.char1 <-

Hello! I need some help with the linear discriminant analysis in R. I have some plant samples (divided into several groups) on which I measured a few quantitative characteristics. Now, I need to infer some classification rules usable for identifying new samples. I have used the function lda from the MASS library in a usual fashion: lda.1 <- lda(groups~char1+char2+char3, data=xxx) I'd

Hi Cole & Michal, I'm sorry for my late response, I just end my journey today. Thank your response, your suggestion is very helpful to me. I have added Michal in this mail, Michal helps me review my initial patchset. (https://www.spinics.net/linux/fedora/libvir/msg191339.html) All concern about this feature is the XML design. My original XML design exposes more details of Qemu.

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
