Re: [R] Import fixed-format ascii file with mixed record types

Thanks again, David I think that this could work. Final questions: 1. I have read that read.fwt could be slow for big tables (my tables have aprox. 16 records, with 176 characters of recordlenght, almost 28MBytes). Could that be a problem? 2. If using read.fwt is not a problem, wouldn't be be

Thanks Jim, As I know nothing about Perl (is it really necessary?), I think that I will try with David's approach. What I want to do is to for a pseudo-panel with my survey data (that is collected periodically), and process it with the survey package. The resulting data set will be big (around 3

Re: [R] merging data frames gives all NAs

Yeah, sometimes the vocabulary we bring to a task does not match up (or "merge" properly) with the vocabulary that the developers use. In this case the merge operation is one that has a precise meaning in database lingo, which apparently you do not have background in. My experience in tryi

Re: [R] merging data frames gives all NAs

I agree. I have a foot of books on R now, for example the R Book by Michael Crowly. But so far, Googling the archives of this list has been the most help. Nonetheless, if I cannot understand the documentation of a function, then the documentation needs to be updated. For example, there needs to be

[R] factorial map?

hello! i'm dealing with the following: i've collected a factor covariable at irregularly placed sampling points along a line with spatial informations, i.e.: dataset<-c(x-coordinates, y-coordinates, level-of-factor) the factor describes the density of vegetation between 0 (no ground cover) and

Re: [R] population variance and sample variance

Probably a simple typo, but just to keep things straight: you want to divide by n when describing the standard deviation of a sample, and divide by n-1 when estimating a population standard deviation (your initial description had it backwards I think). On Tue, Feb 2, 2010 at 5:25 PM, Peng Yu wrot

Anna, Try omitting pkg:RBloomberg. If you really need to use that package, you will have to install the non-CRAN package RDCOMClient from omegahat. I still don't see why toString() wouldn't do its job, even with RBloomberg loaded. -Peter Ehlers anna wrote: Here is the list of the loaded pack
