Dear List members, I would like to ask for advise on quantile regression in R. I am trying to perform an analysis of a relationship between species abundance and its habitat requirements - the habitat requirements are, however, codes - 0,1,2,3... where 0<1<2<3 and the scale is linear - so I would be happy to treat them as continuos The analysis of the data somehow does not work, I am

Last night I sent the bug report below to r-help. I have since then looked at dhyper.c and found: if (NR < 0 || NB < 0 || n <= 0 || n > N) DOMAIN_ERROR; I changed 'n <= 0' to 'n < 0' and then dhyper worked as I wanted. Am I introducing some potentially dangerous behaviour by this change? Goran

my data are matrix with 3 numeric columns. would like to have pairs plot with scatterplots in the upper with hist at the diag and with correlation at the lower. actually default pairs does almost what I want but looks semi awesome. Especially, i didn't find out how to remove the axes from the lower part where I do only want to display the numeric values correlations there and somehow axes

Sorry. Let me try again then. I am trying to find "significant" predictors" from a list of about 44 independent variables. So I started with all 44 variables and ran drop1(sep22lr, test="Chisq")... and then dropped the highest p value from the run. Then I reran the drop1. Model: MIN_Mstocked ~ ORG_CODE + BECLBL08 + PEM_SScat + SOIL_MST_1 + SOIL_NUTR + cE + cN +

I was just pondering: Lets look at Server A with one extra harddisc hdb, where hdb1 is mounted at /mnt/folder. /mnt/folder is the folder which should be mirrored on Server B. So Server B rsyncs rsynch -a -delete server::folder /folder from Server A and gets all the new files and deletes all the files, which doesn't exist on Server A's /mnt/folder anymore. What would happen,

Dear r-help-list: If I use the rpart method like cfit<-rpart(y~.,data=data,...), what kind of tree is stored in cfit? Is it right that this tree is not pruned at all, that it is the full tree? If so, it's up to me to choose a subtree by using the printcp method. In the technical report from Atkinson and Therneau "An Introduction to recursive partitioning using the rpart
