Hi, I have a vector like this: DF <- c("Aetna, Inc.", "Alexander's Inc.", "Allegheny Energy, Inc") For each element in the vector I would like to remove the "incorporated" info, so that my vector looks like this: DF <- c("Aetna", "Alexander's", "Allegheny Energy") That means that I have to strip: strip <-

I want R to read my Microsoft Access database or maybe even a Sybase database. I installed RODBC or at least thought I did. Then I issued the following command: library(RODBC) And got Error in lazyLoadDBfetch(key, datafile, compressed, envhook) : ReadItem: unknown type 241 In addition: Warning message: package 'RODBC' was built under R version 2.3.0 Error: package/namespace

I would really appreciate it if anyone could determine what is going on with the following command. It is only half-working and is losing lots of data. For the life of me I cannot even see the pattern of what it is losing and what it is not. I am attaching the R data set which you can use with the Load Workspace menu function.

How does one create a vector whose contents is the list of variables in a dataframe pertaining to a particular pattern? This is so simple but I cannot find a straightforward answer. I want to be able to pass the contents of that list to a "for" loop. So let us assume that one has a dataframe whose name is Data. And let us assume one had the height of a group of people measured at

I followed the threads that enquired about doing post-hoc tests after doing Kruskal testing. It took me to npmc. But npmc is giving an output I do not understand. I noticed a thread entitled "npmc function: 'x' must be atomic" but there never appeared to be a resolution. > npmc(npmcinput) Error in sort(unique.default(x), na.last = TRUE) : 'x' must be atomic

A while back Gabor Grothendieck suggested that I try http://news.gmane.org/gmane.comp.lang.r.general. This was after I asked how to easily reply to posts on the listserve. Ideally I would like the functionality that I find in Microsoft Outlook Express newsreader for usenet groups or what I find in Google Groups. I started using gmane about 3 weeks ago. I find it fantastic for searching and for

I am involved in a study where, as in most of life, men demonstrate themselves to be recalcitrant. So while we have many probands and most of their mothers we only have about 50% of the trios being complete. I have been running tdt and trio.types. It appears as if it is ignoring the duos. Sometimes a duo can be informative. For instance Father ..missing Mother 1/2 Proband 1/1 This duo shows that

I am about one step away from heaven on earth. I think only one step! I am using dgc.genetics to run a TDT test on thousands of genetic loci. I have learnt (through the help of others on this mailing list) to send the complex output to useful data frames which in turn allow me to look at the big picture and screen the thousands of loci. Resultdt<-lapply(PGWide[,240:290], tdt) the above

I am using dgc.genetics to perform TDT analysis on SNP data from a cohort of trios. I now have a file with about 6008 variables. The first few variables related to the pedigree data such as the pedigree ID the person ID etc. Thereafter each variable is a specific locus or marker. The variables are named by a pattern such as "Genotype.nnnnn" with nnnnn corresponding to a number which

Bottom Line Up Front: How does one reshape genetic data from long to wide? I currently have a lot of data. About 180 individuals (some probands/patients, some parents, rare siblings) and SNP data from 6000 loci on each. The standard formats seem to be something along the lines of Famid, pid, fatid, motid, affected, sex, locus1Allele1, locus1Allele2, locus2Allele1, locus2Allele2, etc In other

Does anyone know if the sib TDT has been implemented in R 1. Spielman, R.S., and Ewens, W.J.

I cannot read google spreadsheets. I get the following error: assignment of an object of class "NULL" is not valid for slot "access" in an object of class "GoogleSpreadsheet"; is(value, "character") is not TRUE RGoogleDocs is on the cusp of brilliance. How can I troubleshoot this apparently last remaining problem? Farrel J. Buchinsky, MD Director,

Power calculations two sample test for proportions is very useful. Is there a way however, to get away from the two samples being of the same size. What would happen if one had n=15 in the one sample and n=45 in the other sample.

This ought to work: resultdt <- lapply(PGWide[, 240:389], function(x, ...) try(tdt(x, ...))) You can then check the class of each component to see which one failed.

I am aware of the R Genetics Project that developed the R library and software called Bioconductor (http://www.bioconductor.org/ ) . How do the two relate to each other? What is the one that the other is not and vice versa? Can anybody link me to something that answers the question? -- Farrel Buchinsky, MD Pediatric Otolaryngologist Allegheny General Hospital Pittsburgh, PA
