Dear R experts, I posted a question last week regarding RSJava error UnsatisfiedLink: eval. But, I did not get any response yet. So, I am trying to work something out. I tried to write something with perl, but it still does not work. In perl, when I used rename which is a Dos command, it worked through the cgi, so did cp (which is not a Dos command, but, it is in my path). And the perl

The gregmisc package contains a function 'perumutations' which generates all permutations of n choose r. It also contains 'combinations' which generates all combinations, and which appears to match your example: > library(gregmisc) Loading required package: MASS Attaching package `gregmisc': The following object(s) are masked from package:base :

Dear R experts, Sorry, I am resending this, since I have not received this mail myself for the past 5 hours. I saw a similar question dated July 2. But there is no answer to it.

Dear R-experts, I have a data file df as the following: genename variable at 1hr variable at 4 hr variable at 10 hr gene1 gene2 . . . gene5000 I would like to have a graph with X-axis as the time point (1hr, 4hr, 10hr), and Y-axis as the value of the variable. So, basically, I want to do a line with the three different values at 1hr , 4hr and 10hr for all the 5000 genes. My purpose is

Folks, Having problems getting started with SJava and request help. I get this error when running .JavaInit() (within RGui 1.5.1, on Windows 2000): Error in .JavaInit() : Couldn't start Java Virtual Machine: Cannot find the Omegahat interface manager class.

I'm working on a project related to document clustering. I know that R has clustering algorithms such as clara, but only supports two distance metrics: euclidian and manhattan, which are not very useful for clustering documents. I was wondering how easy it would be to extend the clustering package in R to support other distance metrics, such as cosine distance, or if there was an API for
