similar to: Cannot allocate large vectors (running out of memory?)

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. 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 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. 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

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

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

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

Hi. I often wind up with many help windows cluttering my RGui screen when running Windows R 2.0.1. Is there an R instruction to close one or more help windows, or an RGui command to close all help windows? Yours truly, /Ronnen. /P.S. E-mailed CC:s of posted replies appreciated.

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

I currently have a data frame with a Fund ID and NAV value. Is it possible to order the data frame and move to separate columns in a new data frame or matrix in R without using a for loop? I suppose I'd like to use a built in function to make it faster because I will have around 60,000 entries to sort and my current program takes too long to do this. I know how to use order, but is there a

Hi all. Is anyone else seeing issues with OpenSSH being slow on OSX High Sierra? In the interests of better test coverage I set one up, however the OpenSSH tests take much longer on it than on much older machines with much slower CPUs. It seems to be due to the vendor-supplied libcrypto being about 20x slower at bignum operations than nominally the same version of LibreSSL compiled locally. If

Hello List, i use dovecot 2.2.22 and have the same problem described here: https://dovecot.org/pipermail/dovecot/2017-November/110020.html I can confirm that sometimes there is a problem with connection to mysql-db, but sometimes not. Reasons for failing are still under investigation by my mates. My current main problem is, that this fail seems to be a one way ticket for dovecot. Even if

Dear All, I would like some advice on creating R packages, passing by reference and oo R. I have created a package that is neither elegant nor extensible and rather cumbersome (it works). I would like to re write the code to make the package distributable (should it be of interest) and easy to maintain. The package is for Bayesian model determination via a reversible jump algorithm and has
