...a new user of R, and I am not able to read/scan external files. I am working in a Linux environment. I have read through the R FAQ and documents and have not been successful using the recommendations. Below are several scripts I've used and the error messages. . I've cc'd Brandon Whitcher because it was recommended in another FAQ. I read that this is a bug that occurs on Windows. Is there is a patch/fix that I can use? I'd appreciate any help with this problem. Thnx, Barbara Chisolm Test2 <- scan("C:\\bac\\TestData2") Error in file(file, "r") : cann...

Hello, I use wavethresh packages to perform wavelet analysis. In particular, I would like to compare 2 signals (vectors) after a wavelet decomposition. I would like to use cor.test function, but this function acts on the entire vector values. I plan to perform a cor.test on each level of the wavelet decomposition, say N. So I will have at the end of a first step N results of cor.test. How can

I have installed both 32-bit and 64-bit versions of R2.12.0 (2010-06-15 r52300) on my Ubuntu 10.04 64-bit system. I observe the following behavior when running the examples from base::connections. There appears to be a problem with seek() on a .gz file when using a 32-bit installation of R2.12.0, but the problem doesn't appear in the 64-bit installation. I realize that seek() has been

Dear list members, I have problem to load data of the library waveslim. After I load the library waveslim and tried to load data ibm data(ibm) Error in file(file, "r") : unable to open connection In addition: Warning message: cannot open file `ibm.txt'' I also tried other data sets without success. It works for other libraries though. Any suggestions? Thanks. Zhu Wang

I have R code to read a binary header file, consisting of several readBin() and readChar() statements. I am currently using version R-2.2.1 (on x86_64, RH EL4) and have received the following error Error in readChar(fid, n = 1) : invalid UTF-8 input in readChar() This is strange because (a) I was able to read in this file successfully in previous versions of R (circa 2005) and (b) it

Dear R users, Has anyone implemented a "matrix log" function in R similar to the function logm() in Matlab? I did a quick R site search and browsed the contributed packages to no avail. The octave function is far too simplistic and fails for the Matlab test matrix. Ideally, the code of Cheng, Higham, and Laub (2001) or something similar could be utilized. Just checking before I
