Consider the following: > x<-list(c(1,2,3),c(4,5,6)) > x[1] [[1]] [1] 1 2 3 > x[2] [[1]] [1] 4 5 6 So far that all seems reasonable. But now there's a problem. I'm used to python, where I would say x[2][1] and get the value 4. But I can't figure out how to do that in R. > x[2][1] [[1]] [1] 4 5 6 > x[2,1] Error in x[2, 1] : incorrect number of dimensions I have

I could do this in various hacky ways, but what's the right way? I have a nice application of the by function, which does what I want. The output looks like this: > auc_stress lab.samples.stress$subid: 2 cortisol amylase 1 919.05 6834.8 ---------------------------------------------------------------------------------------------------------------------------

I have a data frame in wide format. There are six variables that represent two factors in long format 3x2, Valence and Temperature: > head(dpts) File Subj Time Group PainNeg.hot PainNeg.warm SociNeg.hot SociNeg.warm Positiv.hot Positiv.warm Errors 1 WB101_1_1_dp.txt 101 1 MNP 30.700000 13.75000 16.319048 35.166667 30.18333 14.383333 1 2

I made this rather cool plot which I am quite pleased with: http://brainimaging.waisman.wisc.edu/~perlman/data/BeeswarmLinesDemo.pdf However, I feel there must be a better way to do it than what I did. I'm attaching the code to create it, which downloads the data by http so it should run for you if you have the current version of beeswarm installed (which was just updated today,

The right candidate will work closely with neuroscientists seeking to discover new medicines to treat Alzheimer?s disease, bipolar illness, schizophrenia and autism. He/she will be involved in the design and analysis of preclinical experiments covering all aspects of drug discovery from disease target identification through animal model development and de...
