Hello! Does any one know how to modify attributes of files (hide, read only and etc) in Windows Systems using R? I tried to use shell to call system command, but it seems that it doesn't work well. Sometimes it works but sometimes not. Regards! -- Chuanlong Du Department of Statistcis Iowa State University Ames, IA, US 50011 [[alternative HTML version deleted]]

Hello, everyone! Does anyone know whether there's a function in R which can save the content in R console to some file? I'm using Windows system and the usual R console instead of Rstudio.

I downloaded the latest version of R (1.5.0) and issued a read.table() command that used to work with (1.3.1). Unfortunately I erased 1.3.1 from my hard drive after I downloaded R 1.5.0. Here's the command and the error message I get under 1.5.0: > golub1<-read.table("C:/Microarrays/code/data_set_ALL_AML_train.txt",sep="\t",q

At a snail's pace I keep on translating an introduction to R into italian; I have reached the section describing the glm() function, in which some example code is presented. The very last line of code, before the beginning of the section on Poisson models is: ldp <- ld50(coef(fmp)); ldl <- ld50(coef(fmp)); c(ldp, ldl) which of course gives results 43.663 and 43.663; the correct code

Hello, I thought some of you might like to know about a GNU project that is complementary to R in some ways, namely gretl http://ricardo.ecn.wfu.edu/gretl (GNU Regression, Econometrics and Time-series Library). gretl (a library with cli and gui clients, the gui using GTK) is designed to be very user-friendly, and suitable for teaching econometrics. It has a fairly wide variety of least-squares

I'm trying to do a Windows build of Ray Brownrigg's port of the maps library, and running into some problems. There's a makefile for the shared library. I suspect that I just need to change that to get it right, and everything will build properly, but I'm running into trouble. Here's the original makefile, along with my comments about changes: >SRC= mapget.c mapproject.c

I tend to use table() quite a bit for quick "diagnostics", summary, etc. I have wished for a more automatic way of plotting these. One possibility would be something like the following function; The question is if (something like) the following is worth providing (and then maintaining...) at all : plot.table <- function(x, type = "h", ylim = c(0, max(x)), lwd = 2,

I'm using the function htmlParse() in the XML package, and I need a little bit help on error handling while parsing an HTML page. So far I can use either the default way: # error = xmlErrorCumulator(), by default library(XML) doc = htmlParse("http://www.public.iastate.edu/~pdixon/stat500/") # the error message is: # htmlParseStartTag: invalid element name or the tryCatch()

The point estimates produced by wilcox.test are perverse (not wrong, just brain damaged). The Hodges-Lehmann estimator that goes with the signed rank test is the median of the Walsh averages. The Hodges-Lehmann estimator that goes with the rank sum test is the median of the pairwise differences. wilcox.test agrees except that it uses the following very peculiar definition of "sample

Hi dear all, In my laptop(ubuntu 11.10 64bit), I maintained a released R (2.14) and a developmental R, I can specify qplot(..., alpha = ) in R 2.14 , but when I try to use transparency in developmental R, I got a warning message and the plot is clearly not I want. minimal example: > qplot(data = mtcars, x = mpg, y = cyl, alpha = cyl) Warning message: In grid.Call.graphics(L_points, x$x, x$y,

Hi, The documentation I've read indicates that I should be able to get Samba to honor the value of the 'workgroup' variable as set from within an included virtual server configuration file. Given the configuration files below, if I comment out the "workgroup = testwg" line from the main configuration file (smb.conf), then a query of the Samba server (with

Good afternoon, I have been experiencing a lot of crashes working with large vectors in R. Specifically, I am using XTS of length of minimum 120k elements. My problem is that I cannot display the vector (otherwise R crashes), I cannot plot it either (otherwise R crashes). That could be solved by reducing the amount of points. However, I have been performing some statistical opreations on is

I'm trying to build the 1.4.0 development version of R for Windows. I'll be posting problems as they arise, until I give up (or succeed), or someone asks me to stop. 1.
