This really isn't a CentOS specific queation but that is our server OS of choice. I manage a student file server and i would like to add cloud access to it. Basically i would like our students to have access to the same files at home that they have at school. This would allow them to start an asignment at home, finish it at school, and print it off without having to worry about losing their

Dear editor: I'm writing this letter to enquire where can I download the package of "lmtest". Can you send me this package? THanks a lot. Best regards, Shu-Fei Wu

Hi all, Thanks to Dr Paul Murrell in New Zealand to remind me of security consideration. I am releasing version 0.2 with security fix. This version will allow you to add banned R function names in a list. R_PHP_Online is a PHP CGI web interface to run R programs online, with the capability to show graphics online. You can get current version of R_PHP_Online from http://steve-chen.net/R_PHP/

Good Morning, In version 2.x we used smbclient -P in the interface files to print to printers connected to windows machines. I see that in version 3.x that no longer works. What is the equivalent command in 3.x? Thanks Harve Dearing Technical Services VRC Insurance Systems Phone: 818-707-4295 ext 400 Direct: 818-827-2173

Hi boys and girls, This is to let you know that I am writing a new R CGI gateway: TKU-Stat which has its page on http://tkustat.stat.tku.edu.tw (There is an "English" option on main menu) It's based on PHP language, but it's NOT a R <-> PHP API (I am not a good C programmer :( ) It's just a CGI. Basically, I use PHP and some template engine to get inputs/selections

I find this a bit puzzling ... > solve(matrix(c(5, 2, 3, 1), 2, 2), c(Inf, 3)) [1] NaN Inf > solve(matrix(c(5, 2, 3, 1), 2, 2)) %*% c(Inf, 3) [,1] [1,] -Inf [2,] Inf I would expect the answer to be c(-Inf, Inf), so why has the -Inf been replaced by NaN in solve?

I need to wrap a loop inside a function and am having a small bit of difficulty getting the results I need. Below is a replicable example. # define functions pcm <- function(theta,d,score){ exp(rowSums(outer(theta,d[1:score],'-')))/ apply(exp(apply(outer(theta,d, '-'), 1, cumsum)), 2, sum) } foo <- function(theta,items, score){ like.mat <-

Hellow all R fans, I wrote a R program for SCAN: Smallest CANonical Correlation Method for ARIMA(p,d,q) identification. (by Tsay and Tiao (1985)) I don't know if there is already one for this, but since I was unable to find one, so I did it. It's ready to download at the following page http://netstat.stat.tku.edu.tw/download.php I've tested the program and comared the results

Hi, a problem involving postscript bounding boxes: I'm composing three scatterplots into a single figure, postsript for publication. The individual scatterplots should be square, so the overall figure should have a roughly 1:3 sort of aspect ratio. By default however, the overall figure comes out nearly square, and the scatterplots are stretched vertically. I fixed this by adding

Hello, I'm trying to plot a set of 3 dependant variables (y) against 4 predictors (x) in a matrix-like plot, sharing x- an y-axis for all the plot on the same column/line : y1/x1 y1/x2 y1/x3 y1/x4 y2/x1 y2/x2 y2/x3 y2/x4 y3/x1 y3/x2 y3/x3 y3/x4 In fact, this plot is a rectangular selection of the result of pairs(), limited to the relations between x's and y's

Hello. I am new R user, so this question is probably quite stupid, but for the life of me I cannot figure out how to get predications using multivariate linear regression analysis. Single variable predictions work fine. I am trying the following: -- Known y's for known x's1 and x's2 ys <- c(133890, 135000, 135790, 137300, 138130, 139100, 139900, 141120, 141890, 143230, 144000,

Dear all could you please plot many x's and y's with one legend per plot? I would like to thank you in advance for your help Best Regards Alex.

Hi, I'm a novice with levelplot and need some assistance! Basically, I want a window which contains 6 levelplots of equal size presented in 3 columns and 2 rows. I've tried to approach it two ways. The first way leads to this question: Is there any way to concatenate levelplots from a factor vertically as opposed to horizontally? I'd like to pair the levelplots by factor.2 on

Hi, there: Suppose I have a couple of data.frames and each one has five columns (one for x-axis, two for y-axis and two for std of y's.) There is another dimensions (besides x and y) which is continuous. My question is, how to plot such series of data frames in one plot (thus, 3-dimensional plot) AND multiple 2-D plots. I am not familar with R's plotting utilities. Thanks. -- Weiwei

Hello R user, I have following data frame: df=data.frame(id=c(1:10),strata=rep(c(1,2),c(5,5)),y=c( 10,12,10,NA,15,70,NA,NA,55,100),x=c(3,4,5,7,4,10,12,8,3,15)) and I would like to replace NA's with: instead of first NA tapply(na.exclude(df)$y,na.exclude(df)$strata,sum)[1]* *7 */tapply(na.exclude(df)$x,na.exclude(df)$strata,sum)[1] where 7 is the value of x (id=4) in strata 1 where y=NA

Hello, I recently posted a question about my troubles with importing a lattice/trellis figure into latex. To recap, The figure contains 3 scatterplots, so it should have roughly a 1:3 sort of aspect ratio, in order to make each of the scatterplots square. Instead, the whole figure comes out roughly square, so each scatterplot is badly stretched. I fixed this by adding aspect=1/1 to the

Is the following expected behavior? > mkext <- inline::cfunction(language="C", body='return R_MakeExternalPtr(NULL, install("tag"), R_NilValue);') > x <- mkext() > y <- x > attr(y, "foo") <- "bar" > attributes(x) $foo [1] "bar" I would expect that modifying y's attributes should not affect x. [Tested

Hello: I have a question in Math. If we want to get X's and Y's solution, X>0 and Y>0 We have two equation : 2*exp(X)+X^2+3*Y=2*exp(1)+4 3*X+4*(Y^2)=7 How I use R-project to solve above question?? THANKS YOU !!!! HLC [[alternative HTML version deleted]]

Hi, I am wondering how to draw biplot with the same scales on both plots? For example, if the two plots have much different scales, generally the two x-y's are scaled so that the two plots are sitting in the center automatically. How to disable this?
