similar to: Summary re: read.table on Mac OS 10

Hello, I'm a new user of R, and unsure of why I'm getting an error reading external files on my Mac OS 10 machine. I've read through posts that would seem related (and 'R Import/Export' and 'Introduction to R' as well as pertinent sections in V&R's 'Modern Applied Statistics with S-Plus') but to no avail. If anyone has any suggestions,

Thanks a lot, James!! The problem is fixed. On the version 1.4.0 Mac/darwin (the latest available version for this system) the function read.table (which is called from read.delim etc., too) has the bug you explained. Inserting the row nlines <- nlines+1 after lines <- c(lines, line) removes this bug. M. On Friday, February 22, 2002, at 02:33 PM, james.holtman at convergys.com

I am having trouble with the library function of R Version 1.5.0 for Mac OS X Carbon when I try to load libraries that did not come with the R installation. For example, I put the Biobase library from bioconductor.org in the 'library' folder. R cannot find it, even though it can find the pre-installed libraries: > library() # this lists standard libraries such as 'boot',

I have just installed MacPorts 1.7.0 for Leopard using a downloaded .dmg file. Following the download and installation, I looked for the .profile file to change the environment variables, but found that no .profile file was created. When I tried to do so, I got an error message: /Applications/TextEdit.app/Contents/MacOS/TextEdit .profile 2008-12-27 14:19:02.393 TextEdit[47100:10b] ***

Hi there The default option for saving graphics from R (1.9.1) on my Mac is as a pdf file. If I open the file in Acrobat reader it looks really good and crisp, and is obviously saved as vector graphics, since I can zoom in as much as I like and it continues to look really nice. If I import it into MS Word (from office 2000), or Textedit, however, it imports it as a bitmap and unless I save

Hi guys, I'm new in wine debugging, but i need to get content of textbox to console. I tried Code: WINEDEBUG=+edit ./app.exe 2>&1 It gets content of lineedit, but not textedit. Do you have some idea how read content of textbox from win app in wine? Thanks

I installed package plotrix because reading its vignette it looks like it can help me solve a "legend" problem. The package instaleed correctly on my Mac OS/X 10.5.8 But I cannot reproduce the examples centered on function "lgendg". > library(plotrix) > plot(0.5,0.5,xlim=c(0,1),ylim=c(0,1),type="n", + main="Test of grouped legend function") >

Dear colleages in R, I have earlier been working with R in Linux, where reading in a table containing Scandinavian letters ("?", "?", and "?") in the header as part of variable names has not caused any problem whatsoever. However, when trying to do the same in R running on new MacOS-X (with an Intel processor) with the same original text table does not seem to

Hi, I would like to have four plots plotted in the one figure and under each plot the caption (a) ... (d). Using mtext I can get so far: > plot(1:10, exp(1:10), log = "y", xlab = "xlab") > mtext("(a)",side=1,line=4.5) > plot(1:10, exp(1:10), log = "y", xlab = "xlab") > mtext("(b)",side=1,line=4.5) > plot(1:10,

Does anyone know how to interrupt R in RedHat? Neither control-c nor Esc is working. What I don't want to do is close the window or kill the entire R process. Thanks, David This communication is for use by the intended recipient and ...{{dropped}}

Is there a function that provides the Fisher information matrix for a generalized linear model? I do not see how to access the off-diagonal matrix elements of the value returned by glm. (I'm particularly interested in logistic regression.) If not, what is a good way to use R to compute Hessians or other partial derivatives of log likelihoods? I would appreciate any guidance. David

Does anyone know how to use the equivalent of debug() on an S4 method? I would like R to enter the browser not for the generic function, but for the method of the class that I specify.

Could anyone recommend a package for visualizing a likelihood function of two scalar parameters? I would prefer a three-dimensional plot similar to the kind Mathematica is known for, perhaps generated by a package not specific to likelihood. David ______________________________ David R.

Is there any R function that computes the convolution of the double exponential distribution? If not, is there a good way to integrate ((q+x)^n)*exp(-2x) over x from 0 to Inf for any value of q and for any positive integer n? I need to perform the integration within a function with q and n as arguments. The function integrate() is giving me this message: "evaluation of function gave a

Is there a way I can get R to automatically enter the browser inside a user-defined function on the generation of an error? Specifically, I'm trying to debug this: Error in as.double.default(sapply(lis, FUN)) : (list) object cannot be coerced to double In addition: There were 38 warnings (use warnings() to see them) > traceback() 8: as.double.default(sapply(lis, FUN)) 7:

Given a numeric vector of observations, does R have any generic way to estimate the parameters of commonly used distributions (exponential, gamma, etc.) without numerically optimizing the likelihood function?

After reading the help page on set.seed, I am unsure about how to solve the following problem. I need to call function f a thousand times. The list of values returned by f, should be as random as possible. f calls g twice: f <- function(){g1 <- g(1); g2 <- g(2); c(g1; g2)} The function g in turn calls sample and returns a number, but also depends on its argument, so, starting from the
