Hi, This might be me missing something painfully obvious but why does the cube root of the following produce an NaN? > (-4)^(1/3) [1] NaN > As we can see: > (-1.587401)^3 [1] -4 Thanks! Greg

Hi Everyone, I recently have started using R again on a Linux box after spending several years on a Mac. Last I checked, the best way to use R was through EMACS using something like ESS. I remember that being serviceable but not always the most convenient. Is there anything comparable to the mac version of R with its built in console, editor, etc?? thanks! -- View this message in context:

Hi, I have a fairly complex object that I have written a print function for. Thus when I do print(results), the R console shows me a whole bunch of stuff already formatted. What I want to do is to take whatever print(results) shows to console and then put that in a file. I am doing this using the sink command. However, I am unsure as to how to "unsink". Eg, how do I restore output to

I am using read.table to import a text file within R.   There are several "errors" in my text file.  An "extra" quotation mark has inadvertently been included within a few text fields.   e.g. for a pipe (|) delimited text file, I have something similar to this:   1|7|30| "dog" 2|6|25| ""cat" 3|4|20|"" 4|5| 56| "mouse" 5|3|56|

Dear all, I have run into a problem when running some code implemented in the Bioconductor panp-package (applied to my own expression data), whereby gene expression values of known true negative probesets (x) are interpolated onto present/absent p-values (y) between 0 and 1 using the *approxfun - function*{stats}; when I have used R version 2.8, everything had worked fine, however, after updating

Hello all, I am loading a data frame, fitting a model, getting diagnostic plots and they are flagging a couple of observations as problematic. Fair enough, and I want re-fit without them. After I delete an offending row (identified by one of the diagnostic plots), something like data = data[-3,]; then R will no longer print the contents of the data frame; it tells me it is a data frame

Hi, I've looked around but can't find a clear answer to the difference for these two? Any help? Thanks! -- View this message in context: http://old.nabble.com/dfbetas-vs-dfbeta-tp26331704p26331704.html Sent from the R help mailing list archive at Nabble.com.

Hi Everyone, I have a list of vectors like this (in this case it's 3 vectors but assume the vector count and the length of each vector is not known): [[1]] [1] 9 5 7 2 14 4 4 3 [[2]] [1] 3 6 25 2 14 3 3 4 [[3]] [1] 28 4 14 3 14 2 4 5 What I want to do is take the average vertically. Thus I want to do 9+3+28 /3, 5+6+4 /3, etc... and then have it return a vector. I'm

Hi Everyone, I'm running some simulations where eventually I need to table the results. The problem is, that while most simulations I have at least one predicted outcome for each of the six possible categories, sometimes the algorithm assigns all the outcomes and one category is left out. Thus when I try to add the misclassification matrices I get an error. Is there a simple way I can make

Hi Everyone, I am trying to figure out the spatstat package for the first time and am having some trouble. Unfortunately, I can't post my data set but I'll hopefully post enough details for some help. I want to model the intensity of a spatial point process using 2 covariates from my data. After reading through the documentation, I have successfully created 2 "ppp" objects. The
