...0 on aix3.2.5.. Was using 1.9.18p10 before with no problems. I am authenticating through an NT domain (HCHQ) and have smb.conf set so most shares are public (though one gets updated by me every now and then). We never used encrypted passwords. I had 'read only = true' and 'write list = andreww jons' (I also 'force user' so that files are owned by me..) so that everyone else could read, but I could update. This worked well on old samba, but now I appear to have to enable encrypted passwords, make private/smbpasswd and do an initial smbpasswd to set up an entry. However, samba...

Dear users, is anybody of you aware of a R command to perform laplace transform or even its inversion? Thank you very much. Luca

My computer is a pentium 4 running at 2.4 GHz. My R is 1.7.1 I have written a program in R that calls C++. The program spends most of the time in C++ ( > 90% ). R basically deals with output and input. How slower can this be compared with the program I would get from rewriting everything in C++? Thank you.

Hi, I am running a loop to plot multiple plots. In s-plus, it shows multiple pages in the graphic window to allow checking on each plot. but in R, the next plot always overwrite the previous one, so i can only have the last plot produced, is there a way to have multiple pages in the graphic window just like S-plus does? Thanks

Hi, Suppose I have a multidimensional array: tmp <- array(1:8, c(2,2,2)) is there a function out there that, given a one-dimensional array index, will return the separate indices for each array dimension? for instance, tmp[8] is equivalent to tmp[2,2,2]. I'd like to derive the vector (2,2,2) from the index 8. thanks, Brad Buchsbaum

I am brand new to R and would like to know if there is a way to be able to create, save and retrieve a program in R like a script object in S-Plus. I am just not sure how to do this. I'm sure there are many ways to do this ranging from simple to complex, but the simplest way would be best for me. Thanks, in advance... __________________________________________________ Y!

Dear List Members I'm using R to create a trellis plot using the library of Pinheiro & Bates (trellis graph for grouped data). Here is my question: How can I change the format of the axis (x or y) in terms of the number decimal points that should appear on the plot? In other words, I have that for a set of plots in the y-axis the values appear as 0.2,0.3, etc and for another set they

Hey, All Now I have a data set which is n-dimensional. And want to plot the Scatter Plot Matrix which is n by n. Does R have such function to achieve this? Thanks for your point. Fred

Hi! I am a relatively new user of R and I use it to prepare my dissertation. I have come to some very usefull and specific libraries written for S-PLUS 4 and would like to use them in R. Is that possible? I just found out that one of these libraries has already been transfered to R, while 3 others have not. For the matter of beeing more exact I''m interested in the dealing with missing

Nor it does with 'paste' instead
