Quick question:
I am running the following code on some variables that are factors:

following jims assumption (column instead of row indices is what you
want) this also works:
m - matrix(1:20,4)
unique(which(m11, arr.ind = T)[,col])

Dear All,
please help with the following if you can:
we have:
simt -seq(0,147,by=1)
simc -50*exp(-0.01*simt)
out1.2 -data.frame(simt,simc)
AUC -c(0,apply(matrix(simc),2,function(x) (diff(simt)*(x[-1]+x[-length(x)]))/2
))
df -cbind(out1.2,AUC)
z -cumsum(rep(24,max(out1.2$simt/24)))

Hi,
In order to have robust standard errors in R, what would be the command
that can generate results similar to the robust option in STATA? I tried
using the lmrob command from the package robustbase. With that, the
Adjusted R squared is quite different from the normal lm command. This
does

This usually refers to sandwich standard errors aka HC or HC0 in case of
the linear regression model. These
ifelse() often has problems constructing the right type of return value.
if you want to keep the data as a factor (with its existing levels)
use x[condition] - value instead of ifelse(condition, value, x). E.g.,
x - factor(c(Large,Small,Small,XLarge),
levels=c(Small,Med,Large,XLarge))

Hi Sir,
How to use the optim for maximization. I don't understand the
control$fnscale option that is given on help page. It says if the
control$fnscale is negative, the function will be maximized.
Thanks a lot
