Once more into the breech (browsing problems)
...while, but the problem always comes back. We can ping all day
long; the problem is not with the TCP/IP layer. Also, all the
tests in diagnosis.txt work fine. Any ideas anyone? We have no
real network analysis tools, etc. Are we just clueless, or does
this SMB/CIFS stuff just suck the big schween? Can a network card
appear to work but send out crap that confuses other machines?
We're in the process of converting over from 10Base2 to 10Base-T;
is it possible for these kinds of problems to be caused by flaky
coax connectors, bad cable, etc? It seems to me that if it was
really har...

Using MASSv3's example from 8.7 in R?
Dear list!
I am interested in learning about MLE and I wonder whether it is possible
to use the examples for maximum likelihood estimation given in 8.7 in
MASSv3 with R? AFAIU R does not have a direct replacement for S-PLUS's
ms() which the examples use for the fitting, but optim() may be of help
for me. However, I am not sure how I can convert the use of ms() using
optim()--is there an

Dynamic Dictionary Data Type?
Hello!
I have an algorithm which performs lengthy operations and I would like to
cache results. Other languages usually offer a dictionary data type
which I can use as an efficient way to dynamically cache already
calculated results - what's the best way to do this in R?
Best wishes,

Speed Optimization: Faster Way of Accessing data.frame in a Loop?
Hello,
currently I am using code, which basically works like this:
|
| for (i in 1:20) {
| for (j in 1:30) {
| df[i, j, 20] <- df[i,j,27] + df[i,j,30]
| }
| }
df is: `data.frame: 360 obs. of 30 variables'
Do you have any ideas whether I could get this code any faster?
Regards,

Easiest way to get the mean of a row of a data.frame?
Dear r-helpers!
I am kind of new to R.
I would like to calculate the mean of the numbers of this expression:
data(USArrests)
USArrests[row.names(M) == "Alabama",]
class() tells me it's a ``data.frame,'' what I actually desire is to get
all numbers of a row as a vector or a list to let mean() calculate the mean
of the whole row. (I know this doesn't make sense
