Hi all, I am dealing with very large numbers but I am only interested in their last digits. > 244^244 [1] Inf As far as I can tell, the largest number R can take has 308 digits (1+E308). Is there a way I could see the last digits only of 244^244? Many thanks for your help. Vincent Deluard, CFA. -- View this message in context:

Folks, I have a very basic question. The solution eludes me perhaps because of my own lack of creativity. I am not attaching a fully reproducible session because the issue may well be becuase of the way the data file is, and the data file is large (and I don't know whether I can legally distribute it). If people can suggest things that might be wrong in my data or the way that I am reading it,

Hi r users, I am trying to compute the "moving variance" of a large matrix. I now use a loop but I am looking for a faster solution. Here is a sample of the code. Source= matrix(rnorm(400),ncol=100) variances= matrix(rep(NA,4*100),ncol=100) for (i in 1:80) {variances[,i]=apply(Source[,i:(i+80)],1,var)} any idea? Many thanks in advance.

Hi - Think this is quick help. Not sure how to trap what is causing my simple script to run fine in R, but fail immediately when called from rscript. I can put all sorts of traps in the script itself, but when called from the command line the r window simply flashes and closes. There's probably a way to find out why rscript is failing, but I don't know it and can't seem to find it

I don't think it's the path or the slashes. I run other files in this same manner, with the same path to the script itself, and they go off without a hitch. Although this is the first time I am using 3.4.3, and the only script I am using that version of R for at the moment. Having said that, I did TRY reversing the slashes and got the same result. :-) Michael Ashton, CFA Managing

Dear all, As the object of this mail suggests, the methods package is not loaded by default in R2.13 when using Rscript whereas it is loaded when using an interactive session. An example with the metafor package : library(metafor) example(addpoly.rma) this works in an interaction R shell, but put it in a .R file and use it with Rscript, it won't work until you added library(methods)

Fascinating. The script runs fine in 3.2.5, but won't run in 3.4.3 even with ALL lines commented out. I have no idea what that means. I can't imagine I found a 3.4.3 bug no one knows about.

Hi R users, I have a matrix of data similar to: > y=matrix(rnorm(55),ncol=5) I would like to know to which decile each number belongs compared to the numbers in its column. Say y[1,1] is the third decile among y[1:11,1] and y[2,1] is in the second decile I would like get a matrix that would return their ranks in decile, i.e., y[1,1] -> 3 y[2,1] -> 2 Your help is much appreciated!

Dear all- I have a dataset (see a sample below - but the whole dataset is June 2005 - June 2008). The "LST" format is "YYMMDDHHmm" and I would like to get the hourly average of the "mph" for the summer months (spanning all years). I have been trying to use "aggregate" but am not having much success at all! any thoughts would be greatly appreciated.

Dear All- I am trying to merge two data files - they have different date formats and different times zones. I need to match up the date/time of the datasets and then invoke a conditional statement, such as: if dataC$mph is >= 12 then keep dataM$co23 for the corresponding time/date stamp. snippets of data files: *dataC.txt* LST in mph Deg DegF DegF2 % volts Deg

Hi, I am trying to extract data from a database with R in order to produce monthly statistics. I found in the R Website, the package RODBC, RSQLite and others ones which permit this kind of extraction. The database I want to be connected with is a SQLBASE 7.0 database. So, I would like to know if, using one of these package or another one, I could be able to connect with this type of database.

Hi, I'm trying to figure out how anova works in R by translating the examples in Sokal And Rohlf's (1995 3rd edition) Biometry. I've hit a snag with planned comparisons, their box 9.4 and section 9.6. It's a basic anova design: treatment <- factor(rep(c("control", "glucose", "fructose", "gluc+fruct",

Is there any way to "automate" kerberos authentication on Mac OS X? Here's the problem: When a user wants to access samba-3.0.2a -server from a Mac, he/she has to run "kinit" to get the principal ticket. If this is not done, Mac's tools (Finder) will try to authenticate with NTLM, which is and will be disabled on our servers. Of course, this fails miserably. I
