Dear list:
Before going into my problem, R list has been awesome for me ...thank you
for the help. I have a simple problem, however I could get a answer to it...
#my data
myseed <- c(1001:1030)
gend <- function(x){
set.seed(x)
var <- rep(1:4, c(rep(4, 4)))
vary <- rnorm(length(var), 50, 10)
mat <- matrix(sample(c(-1,0,1), c(10*length(var)), replace = TRUE), ncol =

calculating p-values of columns in a dataframe
I have a dataframe ("mydf") that contains "differences of means".
I wish to test whether these differences are significantly different from zero.
Below, I calculate the t-statistic for each column.
What is a "good" method to calculate/look-up the p-value for each column?
mydf=data.frame(a=c(1,-22,3,-4),b=c(5,-6,-7,9))
mymean=mean(mydf)
mysd=sd(mydf)

output". I looked into it and was a little surprised that a t.test
output object does not have a "slot" for the standard error. Of
