Hi, I got this working. i had to get rid of an underscore in one of my variable names to work on RWeb. Thanks for your help though!! Natalie __________________ I think you have to be either honest or careful, since the code you submitted to Rweb is different with your former code! Why the condition was changed from "test<-subset(X, GRADE == 7 & Y_Q10A < 9)" to

Dear R-List members, I want to check if a set of measurements follows better a gamma or a lognormal distribution (see data below). Using shapiro.test I can test for normality (shapiro.test(log (Lt)). To test for gamma (and normal) distribution I would use ks.test but I need to specify its shape and scale. How should I calculate these values in R? I tried > Lt.fit <- glm(Lt ~ 1,

Short example: > str(d <- data.frame(a = I(letters[1:5]))) `data.frame': 5 obs. of 1 variable: $ a:Class 'AsIs' chr [1:5] "a" "b" "c" "d" ... > str(d[TRUE,,drop = FALSE]) `data.frame': 5 obs. of 1 variable: $ a: chr "a" "b" "c" "d" ... The real problem about this is, that as soon

Greetings, I am working on creating an interactive website that will generate R-code for users based in the information they input on the site. Currently, the R-code can be generated and downloaded to be run locally on a computer with R. However, I have noticed a number of applications out there that instead submit the code directly to an R-web server. Some examples seem to be:

As nobody seems to answer my request, I simply post it again. Is there any reason why the r-help-mailinglist should not be converted to a newsgroup? These were the advantages of a newsgroup I mentioned earlier: -) you can easily search the archives -) the discussion is faster (I experience that the R-mailinglist has a lag of about 1 to 2 hours (not for everyone!!!). When I ask a question, I get

I cannot discover how to set or find the working directory in Rweb, so that I can source() a file from the server. The file I source() must refer to a data file in its directory. setwd() does not do anything, and getwd() says that the working directory is in /var/www/cgi-bin/ (on Linux).

Hi, How are you? I have a quick question.... I have code that works perfectly with R desktop, but does not work with RWeb. Could you please tell me how to modify the code below so it will work with RWeb? #Read in txt file happyguys<-read.table("c:/test8.txt", header=TRUE, row.names=1) #Subset the txt file to only include certain values test<-subset(happyguys, GRADE == 7

I'm looking for an optimal approach to access Oracle databases via RWeb applications. I'm new to R but familiar with programming functions and web pages for the S+ Statserver. I'm now going through the motions of migrating S+/Statserver applications to R/RWeb as a feasability exercise. I can access databases using ODBC directly in R or S, and using Statserver, but I have not succeeded

I would want to know if it's possible to plot two histograms on the same graphic in order to compare the bins one to one, like a Excel graphic. If it is possible can you help me to do it, because I don't know the exact R-commands.

In several places, we have the convention that col = NA means `` don't draw '', e.g. for points() or rect(). For col = <vector> this only works when the vector is integer (numeric), but not in other cases. I think this is a bug, even though not in the strict sense, since we don't seem to claim it should work.. Example: plot(1:10, col = c(1:4,NA,NA,4:1)) ## fine

Hi, I've been trying to use several plotting routings that make use of S's par("uin"), the number of user units per inch. For the moment I've substituted all of the occurences of this with par.uin _ function() (par("fin") / c( diff(par("xaxp")[1:2]),diff(par("yaxp")[1:2]))) This seems to work fine for my needs. -Greg
