plot is not keeping the order of variable
Hi, I created a simple data frame with one factor and one numerical variable. The factor was actually a vector of names of techniques to trimm reaction time data. I want to create a plot that shows the value of F test for every trimming method. So the data frame has its trim factor (who has those labels

t-test y distribución de variables
Hola, Estoy analizando unos datos para una tesis doctoral. Durante la investigación se han recogido distintas variables clínicas de dos grupos (n=30 y n=40). Me encuentro que las comparaciones de medias se han realizado mediante t-tests sin preocuparse de estudiar la distribución de las variables. Al revisar si las variables se ajustan a la distribución normal, aunque los QQplots no tienen

Quantile question
Simple Question I have 100x100 matrix and I want to calculte each row's 30,50% quantile ex) a=matrix(rnorm(10000),100,100) quantile(a[1,],c(0.3,0.5)) quantile(a[2,],c(0.3,0.5)) . . . . I want get results at once. so I try quantile(a[1:100,],c(0.3,0.5)) but I can get what I exactly want. How can I calculte that? -- View this message in context:

cat bailing out in a for loop
Dear All, I am trying to calculate the Hardy-Weinberg Equilibrium p-value for 42 SNPs. I am using the function HWE.exact from the package "genetics". In order not to do a lot of coding "by hand", I have a for loop that goes through each column (each column is one SNP) and gives me the p.value for HWE.exact. Unfortunately some SNP have reached fixation and HWE.exact requires a

lots of disk activity keep process from responding
hi all I have something like 3000 log files in a directory (from data collection). At 4am in the morning cron runs a script of mine that essentiallly trims all files in that directory back to a certain size. Basically does a "tail -c XXXX filename > tmp_filename" I have noticed that only around the 4am-4:15 time frame when the trim is happening does my other process log connection
