Dear R-helpers, if I want to read a .dta-file generated by stata 9.0 with read.dta (foreign), I get the message "not a stata version 5-8 .dta-file". I'm using R-2.6.2 and the latest version of the foreign package. Has someone any hint? With many thanks, Albrecht

Hi, I have some scripts creating GNUplot graphs that I would like to convert to R. It would be a great help if there would be a reasonable converter that takes over plot commands and initial settings and put these into R commands (I'm an R beginner and thus this kind of Kickstart would be helpful). Remark: Asking Google for "gnuplot to R conversion" or similar things does not

Dear R Users, I'm trying to find function that allow me to solve one nonlinear equation. Functions that I found are good for optimization problems. Any suggestions are welcome, rob

Like many software assemblies, R is updated frequently. Also, it creates its own release-numbered directory when it is installed. Packages get dumped into the subdirectory "library". I have a personal habit of storing documents related to R packages in the "doc" subdirectory. Here are my questions. (1) How do people manage an upgrade, from 2.6.1, say, to 2.6.2? 2.6.2 will

# PROBLEM WITH ABLINE # I have a question about a seemingly imprecise abline figure which I have come accross now a few times. # After reading variables a and b... a<-c(3729,1796,1956,5177,3201,3138,4265,3042,3745,2060,5713,6811,4184,1221,4700,3171,8913,5565,5500,2428,4841,10428,11197,5946,2783,4842)

I find that after subsetting (you may prefer "conditional selection") a data frame and assigning it to a new object, the str(new object) reflects the original data frame, not the new one: A <- rnorm(20) B <- factor(rep(c("t", "g"), 10)) C <- factor(rep(c("h", "l"), 10)) D <- data.frame(A, B, C) str(D) # reports correctly E <-

I've found where the problem was and a way to solve this problem: One dataset was encoded (and read) as UTF-8 and the other one was encoded (en read) as latin3 In this case, even if at the terminal you see the same characters, R states that the two elements are not equal. Don't know if this is the way it has to be, or this is a bug. Anyway, editing the second file (encoded as latin3)

Hi! I have the following problem that I beleive is a bug: I have a dataframe with one categorical and one numerical vector. The categorical vector has three levels (uc, up and vc). A plot of the vectors with the categorical vector on the x-axis gives a boxplot with three boxes - exactly as expected. If I then use the subset function to make a dataset that only includes two of the levels of

Hi all: I have an example that shows my problem: > test <- data.frame(c("a", "b", "c")) > colnames(test) <- "mm" > sub <- subset(test, mm=="b") > sub$mm [1] b Levels: a b c > levels(sub$mm) [1] "a" "b" "c" How can I reduce the levels to exclusively those which

Dear list, subset has a 'drop' argument that I had often mistaken for the one in [.factor which removes unused levels. Clearly it doesn't work that way, as shown below, d <- data.frame(x = factor(letters[1:15]), y = factor(LETTERS[1:3])) s <- subset(d, y=="A", drop=TRUE) str(s) 'data.frame': 5 obs. of 2 variables: $ x: Factor w/ 15 levels

Which is the proper way to rename a factor? If I do: test$Parc[test$Parc=="Ol?rdola"]<-"Ol?rdola" R complains that Warning message: invalid factor level, NAs generated in: `[<-.factor`(`*tmp*`, test$Parc == "Ol?rdola", value = "Ol?rdola") Thanks Agus -- Dr. Agustin Lobo Institut de Ciencies de la Terra "Jaume Almera" (CSIC) LLuis Sole

I've set layout(matrix(c(1,3,2,4),ncol=2)) and par(mar=c(0, 4, 4, 0) + 0.0) and par(mar=c(0, 0, 4, 3) + 0.0) for the upper-left and upper-right plots, but still get an space between both plots, is there any way to completely eliminate that space?
