...way would be to do this x <- integer(0) for (i in 5) x <- c(x, i:5) But I need to create really long vectors (where the ending value is in the order of 6500) , and using loops is way to slow. I'm looking for a vectorized method. Any help will be welcomed. Julian Julian M.

...rface? b) If I first calculate the distances among points using the Haversine formula, it is possible to calculate the variogram with a matrix of distances among points (where n is the number of observations) and a vector of observation values?

...Full model m2=gam(y~s(x2)) m3=gam(y~s(x1)) ddev1=deviance(m1)-deviance(m2) ddev2=deviance(m1)-deviance(m3) Here, ddev1 would measure the relative proportion of the variability in y explained by x1, and ddev2 would do the same for x2. Does this sound like an appropriate approach? Julian Julian Burgos FAR lab University of Washington

...ious to me how to do this, given that the covariates have different units and ranges of values. Is there any way to provide weights to the covariates directly (for example providing a matrix of n x m values, where n=number of covariates and m=number of observations)? Thanks, Julian Julian M.

Dear all, I am a new user of R. I would like to know how to get fund's returns in percentage (%). For example, I use: R <- ts(read.xls("FundData"), frequency = 12, start = c(1996, 1)) Whith this program, the returns are like 0.0152699. But, I would like to have 1.52%. Please advise me about the function. Thanks! Fabrice

...is close to 0 and 1, and higher at intermediate values. It seems that the best way to go is to model this using the "quasi" family with a logit link and a mu(1-mu) variance. Or I am missing something obvious? I will be thankful for any input.

Dear list, Hello! I have a question about how to print a label in the plot. I am using the following code: <pdf("mel4_chr3_11cancer_cghFLasso.pdf", height=6, width=5);plot(Disease.FL, index=i, type="Single",main="Plot of Labels");dev.off(); But "Plot of Labels" has not been printed. Any suggestions? Thanks a lot! Allen

Hi! I am using R1.5.0. When using functions form lattice the background is dark grey. I have tried to change it using par() but it does not work. By the way, if I use par and the standard functions like hist() there is no problem with the par function. Any hints? Thank in advance, Ignacio Perez Escuela Colombiana de Ingenieria

Hello, I would like to remove some files which have the extension .test for example (data1.test, data2.test ....). Is there another solution to remove them instead of doing it one by one ?
