[R] Extracting the results of a gam smooth

I am conducting a gam smooth and having a devil of a time getting out the answers so I can work with them. Here are the two lines of code: model - gam(y~lo(x, span=0.75, degree=2), family=poisson) resp_pout - predict (model, data.frame (x=x), type = 'response') The problem comes when I try

Hi, you can add a repository for R found on my server: http://fawn.hsu-hh.de ~steuer/SL-10.0-OSS There I provide rpms for R and ESS. You will need e.g. http://mirrors.kernel.org opensuse/distribution/SL-10.0-OSS/inst-source to get a fortran compiler etc. Hope that helps. Detlef On Fri, 14

Re: [R] matching identical row names

Dear Srinivas, Your data are likely in a data frame rather than a matrix (since the columns are heterogeneous), and name is a variable, not the row names of the data frame. There are several ways to do what you want; one simple way, assuming that the data are in a data frame named Data, is

Re: [R] permutation of rows of a matrix

Dear Jose, M[sample(m, m),] will randomly permute the rows of M. [You probably could have figured this out via help.search(permutation), which would have led you to sample().] Regards, John John Fox Department of Sociology McMaster University Hamilton, Ontario

[R] Removing Rows/Records from a Table

I would like to selectively remove rows from a table. I had hoped that I could create a table and selectively add rows with something like NewTable-table(nrow=100, ncol=4) NewTable[1,]-OldTable[10,] but that doesn't work. The former call gives NewTable ncol nrow 4 100 1 while the

Thanks to Berwin Turlach and Petr Pikal for tapply(vec, Fac, mean)[Fac] and Gabor Grothendieck Thomas Lumley for ave(vec,Fac) . Looking at the code for tapply and ave I guess that the latter is to be preferred. Murray Jorgensen Gabor Grothendieck wrote: Look at ?ave ave(vec, Fac)

[R] manual construction of boxwhisker plot

Dear useRs, how can I construct a boxwhisker plot based on the vector fivenum? The challenge I face is as follow: I have a table such as x | fivenum --- ... | (.) ... | (.) and so forth For each observation x I have generated a vector containing the fivenum

Re: [R] permutation of rows of a matrix

help(sample) does not say anything about randomly permuting the rows of a matrix M by using M[sample(m,m),]. Perhaps it could be added as an example of use. John Fox wrote: Dear Jose, M[sample(m, m),] will randomly permute the rows of M. [You probably could have figured this out via

[R] clustering genes / automatically determining # of clusters

Re: [R] permutation of rows of a matrix

Dear Manuel, Although ?sample doesn't specifically describe permuting the rows of a matrix, it does say that sample(x) generates a random permutation of the elements of x (or 1:x). Indexing the rows of the matrix by a permutation of 1:x (where x is the number of rows) doesn't seem to be much of a
