Hi Henrique,

Maybe i didn't express myself good.
The normal syntax is:

If these data are real -- or at least a reasonable facsimile -- then even
though the machines might be considered random -- i.e. a sample from a
potential population of machines -- there are too few of them to get a
reasonable estimate of their variance. Better to treat them as fixed and

Thanks for the great tips for speeding up functions in your response. Those

Hello,
I think I misread the link you sent me yesterday. In any case, the
reason why SAS generates a model with 30 trials whereas R produces
another one with 25 is that, if the parameter for the number of trials
is not specified in the proc/function call, both systems adhere to
different
Note that the memoization optimization is orthogonal
to the simpler optimizations I suggested (don't repeat
calculations in loops, sort the input vector, do a little
math to avoid so many recursions to the leaves). You
can combine them to get
Cmemo1 - function(T, m) {
C - function(lt, m) {

I am sorry for asking this stupid question, but i have been running in circles.
I want to randomly generate a scaling point of between 1 and 10, for say
hundred entries, where the first 10% percent is has rates between 2 and 7, the
next 15% 3 and 7, 20% between 3 and 9, 20% between 3
I just added a new option nlines to plot.Predict to make it easy to get

Dear R users,
I have numerous data sets (csv files) saved in the folder which has the same
name as individual data.
(i.e data x1 saved in x1 folder, data x2 in x2 folder etc)

assign this inputted value to an object so

I've been trying to filling in the missing variables in a matrix with the
mean from the column they are in. So the following code does this just fine.

Try this:
fill.in.1 - function(x) ifelse(is.na(x), mean(x, na.rm = TRUE), x)

or
fill.in.2 - function(x) replace(x, is.na(x), mean(x, na.rm = TRUE))
apply(data, 2, fill.in.2)
Note that in both cases a column containing only NAs will be filled
with NaN's.
