I have a list of data frames which I would like to combine into one data
frame doing something like rbind. I wish to combine in column order and
not by names. However, there are issues.
The number of columns is not the same for each data frame. This is an
intermediate step to a problem and the

Thanks I was able to find it in the help doc.
x <- c(1,2,4,6,8,9,10,12,13,14,18,20)
y <- c(4,5,3,6,7,4,8,9,12,4,7,5)
mydata <- data.frame(x,y)
plot(mydata)
rect(5,0,8,8, col=rgb(0,1,0,alpha=0.2), border=F)

Hi Kelly,
You seem to be testing the two "years" independently, so here is a
possible solution:
npg<-16
futility1<-futility2<-psignif1<-psignif2<-nrep<-0
while(!futility1 && !futility2 && !psignif1 && !psignif2 && nrep < 1) {
control_respond1<-sum(runif(npg,0,1) < 0.05)
control_respond2<-sum

regarding gmtoff. In short, it is implementation-dependent.

The loop won't stop unless you tell it to stop, and I don't see any place where
you told it to stop.

I am working on a clinical trial simulation with two groups, treatment and
placebo, and the outcome is dichotomous (recovery or no recovery) . I would
like to stop my loop if either of my conditions are met:
1) futility - there are no responses to treatment in the treatment group.
2) the p-value i
Is it possible for someone to explain what is going on here? I would expect
that `as.POSIXlt` would be able to accept `datestring` and return all the
elements without having to convert it using `as.POSIXct` first. Do
`as.POSIXlt` and `as.POSIXct` do different things with the `tz` arg?

Factor Data Type, indeed, is of typeof() Numeric.
Try converting that column to character with as.character()
Class transformation then must work :)

Hi,
In the Caret package, in one of the training model method for
classification , penalised multinomial regression has been used? I could
not find anywhere how the penalised parameters have been chosen here . I
need the statistical methods that have been used. Can someone please help
me?
