similar to: multiple comparisons

I'm working with large data frames and running out of memory. I hope some of you may be able to suggest a more efficient approach. I have grid/lattice data representing a time series of 1 m2 quadrats in a grassland: Each 1 cm2 cell or pixel contains one ecological state (ie grass or bare ground). The goal is to calculate, for each cell, the transition probabilities to all available

Is there a fonction for multiple comparison tests (similar to "multicomp" in Splus) in a package of R? Thanks in advance for any hint...

I suppose that multcomp in R and multicomp in S-Plus are related and it appears that it is possible to use multicomp with lme in S-Plus given the following correspondence on s-news sally.rodriguez at philips.com 12:57 p.m. 24/04/03 -0400 7 [S] LME summary and multicomp.default() Is it possible to use multicomp with lme in R and if so what is the syntax from a simple readily available

[Moderator: This was erronously sent to R-announce, and filtered fortunately ] Hi, This is my first time to use R. I'm wondering which function I can use to do multiple comparison. I have an lm object and want to do multiple comparison based on this object. Splus has a function multicomp() but I could not find a similar one in R. Thanks in advance. Really appreciate it. Julie

I'm working on a program that loads several large data files. I'm using ddply (plyr is really awesome) but I want to minimize the amount of times a large data file is read in. One solution is to keep track of which data file is open with a global variable and then change the currently open data file globally as needed. However, I'm unclear on how to alter a global variable

In the model: lm.1 <- lm(variable ~ BLOC + TIL * YEAR , data=selvanera) I found TIL*YEAR interaction significant. Then I am trying to compare means of the different levels of TIL inside every YEAR using: mc.2 <- glht(lm.1, linfct = mcp(TIL*YEAR="Tukey")) summary(mc.2, test = univariate()) but it does not work. There is any way of doing this, like the SLICE option in

Dear R-listers, I am trying to compute simultaneous confidence intervals with simint from the package multcomp. 230 measures (abundance) have been taken in 23 sites (factor) of a data.frame (donnees: a file can be sent on request, saved with save(donnees,file="donnees")). I would like to get all pairwise comparisons with : mc<- simint(ren~ID,type="Tukey",data=donnees) I

I am using R for a class which uses S. Often I can not find functions that in S but not in R, example, multicomp(). What is your advise.

Dear R people, I have heard rumors of a function called (I believe) multicomp in S+ for doing multiple comparisons for linear models. It doesn't seem to be in the version of R I am using, 0.90.0. Is there something equivalent to this in R, or does it simply not exist? I see there is are more recent versions of R. For my platform, SuSE Linux, the most recent rpm available appears to be

I'm working with a few functions (e.g. do.base.descriptions in the netstat package) that, in addition to returning an object with variables I want to extract, also print output. There is no way to turn this default printing behavior off in many of the functions. Is there a blanket way to suppress such printing, say, within a loop or a ddply statement? Thanks! -Jarrett

Dear list members, First of all thank you for your helpful advices. After your answeres to my firt mail I studied a lot (R-News n?5) and I tried to perform my analysis: First, to fit a GLM with a nested design I decided to use the function "lmer" in package "lme4" as suggested by Spencer Graves and Filippo Piro. I remember to you that my data were: land use classes, 3 levels

Hello, I see that "mclust" is a pacakge that handles fitting mixtures of normals. Are there any other packages out that that can handle mixtures of gammas or other exponentials? Additionally, are there any packages out there that can fit bimodal distributions without mixtures? i.e., Cobb et al. 1983 using moment recursion relations? Thank you! mw Marion Wittmann, Ph.D.

I think you're missing a point here. Two different checksum algorithms are used in concert, the Adler-based one and the MD5 one. I SSE-optimized the Adler-based one. The Adler-based hash is used to _find_ blocks that might have shifted, while the MD5 hash is a strong cryptographic hash used to _verify_ blocks and files. You wouldn't want to replace the MD5 hash with the Adler-based hash,

Hi, Marion, I believe the package FlexMix provides a more generalized version of finite mixture modeling than is found in mclust/mclust02.

Hello: I installed R-WinEdit according to the instructions, including those for setting the editor and pager options. Doesn''t seem to work--when I try to edit a file, I get the following: > > options(editor="\"c:/program files/winedt/winedt\" -c=\"R-WinEdt-edit\" > -e=r.ini -V") > > getOption("editor") >[1]
