I have 4 years of data and for each year, I have initialize the value so now for fitting the model, I want to remove the initial value and get the model based on remaining data set. Could anyone can help on this? I want to get linear model based on fourth column and 13th column but need to remove the initial value for each year and each treatment ( the second column I have 1:36) . Thank you,

R-Users, Hopefully someone can shed some light on these questions as I had little luck searching the archives (although I probably missed something in my search due to the search phrase). I estimated multinomial probabilities for some count data (number successful offspring) ranging from 0 to 8 (9 possible response categories). I constructed a barplot (using barplot2) and I want to

Hi. I am using Windows version of R 1.8.1. Being somewhat new to survival analysis, I am trying to compare cph (Design) with coxph (survival) for use with a survival data set. I was wondering why cph and coxph provide me with different confidence intervals for the hazard ratios for one of the variables. I was wondering if I am doing something wrong? Or if the two functions are calculating hazard

Hi, I am beginning to learn R and have a data table that I would like to produce a microarray-like plot.

I would like to assign colors to the first three columns

Hello All, I have problem on workstations with PC-DOS 2000 with MS Network Client 3.0 connected to Samba 3.0.14a-0.4 (default on SLES 9) when I want to use ARJ.EXE (latest version 2.84) and unpack archive xxxx.arj. When this archive is on network drive shared by samba unpacking does infinite loop. For example arj l x:\xxx.arj produce never ending listing (and start of this listing is very slow).

I am having difficulty understanding how I would constrain a data set by filtering out 'records' based on certain criteria. Using SQL I could query using 'select * from my.data where LithClass in ('sand', 'clay')' or some such. Using subset, there seem to be ghosts left behind (that is, all of the LithClass *.Labels* remain after subset) > dput(tcc)

Hello there, I am not quite sure how to interpret the output of Rprof (in the following the output I was staring at). I was poking around the web a little bit for documentation but without much success. I guess if I want to figure out what takes so long in my code the 2nd table $by.total and the total.pct column (pct = percent) is the most helpful. What does it mean that [ or [.data.frame is

Dear list members, I am new member and fairly new into R world! I hope what I have is not beyond the purpose of this list. I did first search for similar experimental designs without success. I want to perform an ANOVA analysis using the aov() function. I am not 100% sure that I have it right. If anyone can help me, that will be greatly appreciated. My design is not balanced for any of the

Hi. I'm running Samba 2.2.2 and Linux 2.4.7 on a dual PPro-200/256KB server. The relevant NIC is an Intel EtherExpress PRO/100+. The problem I'm having is that certain programs will swamp the server; the load will spike immediately to 50% (i.e., 100% on one CPU) and performance will, naturally, bite. Having another active connection to the server at the same time causes _monster_

Hi, Thanks for the reproducible example. Looking at str(datn) would give you a clue. STATUS is a factor because it contains character values. Factor levels by default are alphabetical with numbers first, but you can change those. > str(datn) 'data.frame': 36 obs. of 3 variables: $ LEVEL : Factor w/ 4 levels "DIPLOMA","MATRIC",..: 1 1 1 1 1 1 1 1 1 4 ... $

I had suggested having size metrics from somewhat larger applications such as Chrome, Webkit, or Firefox; clang itself; and maybe some of our internal binaries with rough size brackets?

I work on Windows, R version 2.4.1. I'm very new with R! I am trying to build a classification tree using rpart but, although the matrix has 108 variables, the program builds a tree with only one split using one variable! I know it is probable that only one variable is informative, but I think it's unlikely. I was wondering if someone can help me identify if I'm doing something

Hi, I had been experiencing a problem on our dedicated server running Centos 5, and unable to successfully track down the problem. Since about 6 days ago, I noticed a spike in load/CPU utilization which went from a typical 0.2x-0.3x to 3.x. At the same time, average traffic also went up and so did the log usage. Prior to this, the server was working fine and there had been no changes to the
