The partial R-square (or coefficient of partial determination, or squared partial correlation coefficients) measures the marginal contribution of one explanatory variable when all others are already included in multiple linear regression model. The following link has very clear explanations on partial and semi-partial correlation: http://www.psy.jhu.edu/~ashelton/courses/stats315/week2.pdf In

Hi, I am very new to R and I've been trying to work through the R book to gain a better idea of the code (which is also completely new to me). Initially I imputed my data from a text file and that seemed to work ok, but I'm trying to examine linear relationships between gdist and gair, gdist and gsub, m6dist and m6air, etc. This didn't work and I think it might have something to do

Greetings. I am trying to list all keys in a java.util.HashMap field. The Java code to do this looks like: # Collection c = hMap.values(); # # //obtain an Iterator for Collection # Iterator itr = c.iterator(); # # //iterate through HashMap values iterator # while(itr.hasNext()) System.out.println(itr.next()); So, I took a stab at the ruby version: # I have a java hashmap called fields

This is related to the general question of efficiency of unwinds. I'm mulling over whether to use the Java-style or Python-style iterator protocol for my language. The Python style is to have a special exception (StopIteration) that is thrown when the end of the sequence is reached. The Java style is to have a separate "hasNext" method on the iterator object that says whether or

I apologize that I've asked a similar question before, but being new to R I don't think I did a very good job of formating the question. I've included a text file since the date set is somewhat large. What I have is a huge string of numbers in a text file. The numbers are all separated by comma's and the groups are separated by a semicolon. What I would like to do is read each

Hello, Been using Xapian and the Java bindings for years, all was working great, and I all of a sudden decided to upgrade to the latest 1.2.12 and use the new java-swig bindings instead of the old hand-crafted JNI which I think have been deprecated now. I'm struggling with the new design of the TermIterator. More specifically, I can't tell when I've reached the end of the list of

Hi folks, I am running a very simple regression using mylm <- lm(mass ~ tarsus, na.action=na.exclude) I would like the use the residuals from this analysis for more regression but I'm running into a snag when I try cbind(mylm$residuals, mydata) # where my data is the original data set The error tells me that it cannot use cbind because the length of mylm$residuals is

Hi, I'm using R-2.12 on a linux 64bit machine. When I run a chunk of code inside a foreach() %do% { ...} or %dopar% {...} (with doMC backend) I keep getting a segfault. Running the *same* code within lapply(something, function(x) ... ) doesn't result in any segfaults. I'll paste the output below, but I'm not sure it would be helpful. I'm more curious how to go about smoking
