Hello. I have an R program that calls gawk (GNU Awk 3.06 for Windows) from within pipe() to preprocess a large file before it is read into a data frame with read.table(). I've recently upgraded from Win98SE to WinXP, and have also upgraded from R1.5.0 to R1.6.1 over the past month or so. This program worked before the upgrade(s), but now fails. I observe the following sort of behavior with

(I'm reposting this message because the original has not appeared after about 2 days. Sorry if it shows up twice.) Hello. First, thanks to those who responded to my recent inquiry about using contour() over arbitrary (x,y) by mentioning the interp() function in the akima package. That worked nicely. Now for a new question: I would like to use a pair of prediction intervals to

Hi. The following statement works fine in R-win 1.8.0, but yields a syntax error in R-win 2.0.1 (and possibly in other versions after 1.8.0): plot(c(1,2),main=expression(a==b==c)) I note that the following workaround executes successfully in both versions of R... plot(c(1,2),main=expression(a*"="*b*"="*c)) ...but I don't really understand

Hi. Can anyone suggest a simple way to obtain in R a list of vector coordinates of the following form? The code below is Mathematica. In[5]:= Flatten[Table[{i,j,k},{i,3},{j,4},{k,5}], 2] Out[5]= {{1,1,1},{1,1,2},{1,1,3},{1,1,4},{1,1,5},{1,2,1},{1,2,2},{1,2,3},{1 ,2,4},{1,2, 5},{1,3,1},{1,3,2},{1,3,3},{1,3,4},{1,3,5},{1,4,1},{1,4,2},{1,4,3}, {1,4,

Hello. Is it possible to set specify the font used by legend()? I would like to specify a fixed-width font so that I can line up parts of vertically stacked curve labels. For example, it would be nice if I could align the names, ages, and weights in the following three curve labels: Bob age=7 weight=100 Alexander age=13 weight=150 Susan age=20 weight=130 Is there perhaps a clever

Hi. As shown in the simplified example below, I'm having trouble allocating memory for large vectors, even though it would appear that there is more than enough memory available. That is, even with a memory limit of 1500 MB, R 2.6.1 (Win) will allocate memory for a first vector of 285 MB, but not for a second vector of the same size. Forcing garbage collection does not seem

Hello. I have an XYY series that I would like to graph with matplot() or some other single function that will do the trick. The X in question is a vector of POSIXt values obtained from strptime(). Is it possible to tell matplot() how to handle POSIXt x values? I have examined the examples at http://lark.cc.ukans.edu/~pauljohn/R/statsRus.html#5.22 , but would prefer not have to overlay the

Hello. Is there an easy-to-use contour plot function analogous to scatterplot3d that can draw handle a dataset of arbitrary (x,y,z) triplets? That is, say x, y, and z are each measured quanties, and exhibit neither order nor regularity. I looked at the lattice package function "contourplot" but it seems complicated, and it's not clear from the documentation whether it can

Hi. Is there an analog to abline() that can be used to plot a polynomial fit? For example, I can draw the straight-line fit fit <- lm(y ~ x) via abline(coef=fit$coef) but I'm not sure how to draw the polynomial fit fit <- lm(y ~ poly(x,2)) I do see the function curve(), but not how to prepare an expr for curve() based on the coefficients returned by the polynomial

Hi. I'm having a little difficulty with R1.5.1. To wit: (1) Can anyone explain the following behavior? > a=strptime("2002-06-01 12:15:01","%Y-%m-%d %H:%M:%S") > a [1] "2002-06-01 12:15:01" > a+0 [1] "1932-04-25 21:46:45" > a+3600 [1] "1932-04-25 22:46:45" (2) Can anyone recommend an introductory R text other than that

Hello, I have read recent posts on this topic (Dr. Ronnen Levinson's Monday 02:39:55 pm), but before I install a 64 bit system, and purchase more RAM, I want to make sure I understand this interesting issue. I was attempting to plot a data frame containing Dow Jones stock information: > length(Date) [1] 19957 > length(Close) [1] 19957 > head(DowJones) Date Open High

I just installed R-2.3.1pat under Windows XP as well as the associated RWinEdt. If I start RGui from its shortcut (but do _not_ also start RWinEdt) and then try to execute demo() or help(), I get a RWinEdt pop-up error window with message: File "D:\WP\WinEdtData\WinEdt\D:/WP/WinEdtData/WinEdt/R.ini" does not exist! Qualifier -e/-E does not specify an existing file! First

Hi, Using the Rconsole file I can specify the size and location of the Rgui windows on NT. e.g. # Dimensions (in characters) of the console. rows = 51 columns = 100 How can I specify the size of the help windows that popups when I ask for help? e.g. '?help' I would like the popup window to have say rows = 51 and columns = 100, just like the main window but a different location on the

Full_Name: Byron Ellis Version: 1.2.3 OS: Windows 2000 Server Submission from: (NULL) (140.247.105.95) In Rgui when attempting to resize the console the system locks for a second (cursor locks up, etc) and then either returns to normal for a second before crashing or just crashes when we start moving again (the former happens more often when making things bigger, the latter when the console is

Dear all: Now RGui on windows no HighDPI awareness.try add HighDPI awareness to RGui in last two days. I write an initial POC(just for verify and only SystemDPI awareness partial implemented) , try to mod graphapp used in R to implemented DPI scaling. it seems works on my laptop , but need further test. So I post the patch https://github.com/armgong/misc-r-patch/blob/main/dpi-c-code.diff

Hi, all, Using RGui, is it possible to create a graphics window that can be moved outside of the RGui window? (This can be done--in fact must be done--using Rterm, but I wish to use RGui.) My interest for this is to use two monitors: in "my private monitor" I wish to execute R code in the Rgui window; in "the public monitor" I want the audience to see the results in the

Hi, i would like to find out more on how Rgui works. Is there any documentation that details how RGui interfaces with the R language & environment. So, i would like to know things such as: - What language is RGui built in (source available?) - What language is RTerm built in? - how does the output of an R command get directed to the terminal window in RGui? It seems to me that RGui is RTerm

ISSUE: It looks like Rgui.exe never processes ~/.Renviron - only ./.Renviron.
