...orrect PATH for building packages. (The master Windows PATH points to different versions of make and grep that I prefer for my usual work.) Two questions: 1. GUIDANCE. Is the Peter Rossi document now the best place to look for detailed guidance? I have located it at http://www1.appstate.edu/~arnholta/Software/MakingPackagesUnderWindows.pdf The links to it on the R Project Website are no longer good. I am also reading at the latest version of "Writing R Extensions." 2. LATEX. In Rossi's paper, fpTeX is recommended (I use VTeX in everyday work). However, fpTeX has been discontin...

Hi, Suppose I have a matrix with, say 12 columns. I would like to extract out column 2 ~ 8 and 11 ~ 12 then combine them together. I tried with success to extract out the columns by doing: foo <- test[,2:8] goo <- test[,11:12] However then I am having trouble combining foo and goo. Helps are appreciated!

Hello- Since my data bank in SPSS has > 40 variables, I think that R crashes because of the memory limit. In Maindonald?s UsingR text, on pg 3, there?s a footnote that reads: "If you want larger memory space than the default you may want a target akin to <path to binary>\rw091\bin\rgui.exe --visize 30M --nsize 1000K [The default is --vsize 6M --nsize 250K

Dear all, I found a discrepancy while performing a power calculation for a two sample t-test in R and S-PLUS, respectively. For given values of sample number (5 each), sd (0.2) , significance level (0.01), and a desired power (80%) I looked for the difference in means. These values differ: 0.5488882 in R and 0.4322771 in S-PLUS (see dump below). Did I overlook any detail or confuse some

Hello, I'm looking for a textbook that can explain some of the math behind the intro-to-intermediate stuff like ANOVA, multiple regression, non- parametric tests, etc. A little background: I took an intro stats course last year and would like to further my education. Being as that was the highest (and only) stats class the local community college offers, it looks like I'm on
