Writing responses to the R-Help list
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

Reshaping genetic data from long to wide
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

Unequal sample sizes when calculating power
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.

Installing a package yet it will not work.
I want R to read my Microsoft Access database or maybe even a Sybase database. I installed RODBC or at least thought I did.

Npmc for doing post-hoc after Kruskal
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

Incomplete Trio in TDT analysis
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
