similar to: strange problem with strptime and date variable

Hi All, I have been experiencing a strange issue ever since I upgraded my R and the packages. I cannot plot anything to the CairoPNG device.For an example:> Cairo(600, 600, file="plot.png", type="png", bg="white")> plot(1:10)> dev.off()will create an empty plot.png file. I am running R 2.12.1 (32bit) on Windows 7 (64bit). ----------------------------->

Dear all, I noticed in the latest R version (R.2.12.1) that the readPNG gives following warning when running the example code in the help file (or when using any other png for that matter) : 50: In rasterImage(img, 1.2, 1.27, 1.8, 1.73) : Per-pixel alpha not supported on this device No picture is shown, and code I used to be able to run, doesn't run any more. > sessionInfo() R version

My day for dumb questions. How do I increase the type size in the Rgui console in Windows? (R-2.13.0, Windows 7) It looked to me that I just needed to change the font spec in Rconsole but that does not seem to be working. The R FAQ for Windows has a reference in Q3.4 to changing fonts, (Q5.2), but I don't see anything relevant there. Rconsole originally was: font = TT Courier New points =

Hi, from example(capitalize) of the Hmisc package (v 0.8.3) you get: > capitalize(c("Hello", "bob", "daN")) [1] "Hello" "Bob" "daN" Is that "daN" correct? If so, then this behavior that only *all lowercase strings*, which the code indicates, will be capitalized is not documented. > Hmisc::capitalize function

I am new to using odfWeave but I have encountered a problem running both the example in the help file as well as another file.? I am not sure how to correct the error. First example: library(odfWeave) filein <- 'c:\\my documents\\example01_in.odt' fileout <- 'c:\\my documents\\example01.odt' odfWeave(filein, fileout, control = odfWeaveControl(cleanup = T)) error:

If I run the following: > windows() > > bringToTop(-1) > > interactive() [1] TRUE > > run <- readline(prompt = "Continue (Yes = 1, No = 2):") Continue (Yes = 1, No = 2): > dummy <- 1 > run [1] "" it does not allow user input though the session is interactive (it jumps right over the readline command). It would be great

Dear all, Sweave chokes when using "\\" in the path to the Rnw file. Using "/" works fine. The problem is that Eclipse+StatET uses "\\" in the filename. And example of the error, traceback and sessionInfo are given below. Best regards, Thierry > Sweave("Q:\\BMK\\cursussen\\interne_opleiding\\deelnemerslijst.Rnw", syntax="SweaveSyntaxNoweb")

Hello, I would like to fit correlation structures with nlme, but R crashes. My data is similar to the "growth of orange trees" example from Pinheiro and Bates (2000), but data are not equally spaced in time, as the last observation is taken after 6 days ( and not 2 as the others). This is the code I'm using: library(nlme)

Clearly, I don't understand what order() is doing and as ususl the help for order seems to only confuse me more. For some reason I just don't follow the examples there. I must be missing something about the data frame sort there but what? I originally wanted to reverse-order my data frame df1 (see below) by aa (a factor) but since this was not working I decided to simplify and order by

Dear all, ggplot gives me an error when trying to plot time series data using a date variable as the x axis. g<-structure(list(Date = c("2011-12-23", "2011-12-30", "2012-01-06", "2011-12-23", "2011-12-30", "2012-01-06", "2011-12-23", "2011-12-30", "2012-01-06"), variable = structure(c(1L, 1L, 1L, 2L, 2L,

Hello dear R help members. I am trying to understand the anova.rq, and I am finding something which I can not explain (is it a bug?!): The example is for when we have 3 nested models. I run the anova once on the two models, and again on the three models. I expect that the p.value for the comparison of model 1 and model 2 would remain the same, whether or not I add a third model to be compared

Dear R community I have tried to run the diagnostics on my lm object with the gvlma package but it gave me an error with the following message: Non compatible arguments I post here my syntax and session info: RegreC3<-lm(Classification_Score~C3L+Age_+Dx,data=DB1)summary(RegreC3) library(gvlma)gvmodel <- gvlma(RegreC3) R version 2.13.1 (2011-07-08)Platform: i386-pc-mingw32/i386 (32-bit)

Hi all, I found that the two different versions of "survival" packages, namely 2.36-5 vs. 2.36-8 or later, give different results for coxph function. Please see below and the data is attached. The second one was done on Linux, but Windows gave the same results. Could you please let me know which one I should trust? Thanks, ...Tao #####============================ R2.13.0,

This problem is likely to be specific to Windows, and particularly Win7. After a successful build of a package (R CMD build addendum), I immediately run an R CMD check for the same package. Not always, but _very_ often, I get the following error: C:\Users\nisabbe\Documents\@Doctoraat\R>R CMD check addendum Loading required package: tcltk Loading Tcl/Tk interface ... done Loading

Dear all, I wish to create a POSIXct variable from date and time variables using the ymd_hm function in package lubridate. In some cases data for time is missing, which causes a problem for ymd_hm. I wish to find a smooth way to handle this. # Some example data: x <- data.frame(date = c("2011-09-22", "2011-07-28"), time = c("15:00", NA)) x # paste date and

Hi, This looks OK: > x <- c("_1_", "1_9", "2_9") > rank(x) [1] 1 2 3 But this does not: > xa <- paste(x, "a", sep="") > xa [1] "_1_a" "1_9a" "2_9a" > rank(xa) [1] 2 1 3 Cheers, H. > sessionInfo() R version 2.14.0 (2011-10-31) Platform: x86_64-unknown-linux-gnu (64-bit) locale: [1]

Dear users, By running the script below, R crashes systematically at the last command, namely dev.off(), on Windows 7, but not on Windows XP. I therefore don't provide a reproducible example and do not really extract the relevant parts of the script because it has most likely nothing to do with the script itself. I can do it though if you think it might be relevant. R crashes on Windows

On a Unix machine I ran caret::rfe using the multicore package, and I saved the resulting object using save(lm2, file = "lm2.RData"). [Reproducible example below.] When I try to load("lm2.RData") on my Windows laptop, I get Error in loadNamespace(name) : there is no package called 'multicore' I completely understand the error and I would like to ignore it and

R Gurus: This sounds not a FAQ. I upgraded WinEdt from 5.4 to 5.5 , following load RWinEdt, R-WinEdt editor appears. There are more menu items and task icons in this version, but I failed to find a pull down menu or task icon to send code to R.
