similar to: nls() error

Hi I am using the nls function in R however it is causing the following error: REAL() can only be applied to a 'numeric', not a 'logical' Using traceback shows this occurs after the .Call(R_nls_iter, m, ctrl, trace) call. However I do not know how to debug this further to find out what is causing the error. The data I give the nls call definitely starts as numeric. The

All, I have used package.skeleton, edited the .Rd files and the DESCRIPTON file. In one of my package functions I am using RODBC so I have a line of code that reads: require(RODBC). In my DESCRIPTION file I have the following relevant line: Depends: R (>= 2.9.0), RODBC However, when I do a check (Rcmd check my_package_name) I get this warning: * checking for unstated dependencies in R code

Dear R-Group, I have a function that sorts a data frame and oneo of the lines in the function is: vars <- unlist(strsplit(formc, "[\\+\\-]")) The function works fine and the above line is always reached.

Hi, I have a contour plot and I want to shade a polygon (the area below a line) but the polygon shading wipes out the contour lines. Does anybody know how to shade the polygon and still see the contour lines? Thanks. Jeff

Hi, For another trainingset I get this error message, which again is rather cryptic to me: Setting default kernel parameters Error in array(0, c(n, p)) : 'dim' specifies too large an array RMate stopped at line 0 of selection Calls: rvm ... .local -> backsolve -> as.matrix -> chol -> diag -> array thanks for any suggestions!

Dear All, I want to compare formulas resulting from using stepAIC() on glm() objects. I have 2 different formulas, say F1 and F2, which consist of about 10 factors (Y~A+B+C+...) but one has an interaction term (A:B) while the other doesn't. But when I perform F1==F2 it comes back as TRUE. Is there a proper way to compare formulas? ------------------------------------------- Jeffrey M

Hello, I want to plot 3 boxplots [ par(mfrow=c(3,1)) ] but the first one has 8 groups, the 2nd has 7 and the third has 6. But I the groups to line up: 1 2 3 4 5 6 7 8 2 3 4 5 6 7 8 3 4 5 6 7 8 where the numbers actually refer to years. I suspect I have to manipulate the function bxp(). Is there a relatively simple way to do this? Thanks for any help. Jeff Breiwick NMFS, Seattle

Dear all, I've recently had some issues getting my package to successfully "check". This was on R-Forge, so it's not obvious for me to provide SessionInfo or the likes (if necessary, Stefan can chime in?). After some research (mainly by Stefan Theussler, driving force behind R-Forge), this turned out to be the root cause: On R-Forge, the version of R installed was the

Hi, I am using R 2.3.0 and my .First() file has the following line which causes a warning: attach(what="c:/r/jmb/.RData", pos=3) I get the following message after .First() is loaded: During startup - Warning message: use of NULL environment is deprecated Is there a simple fix that will eliminate this warning message? Thanks. J. Breiwick

Hello, I have a workspace that contains a number of functions I want to put in a library. Under R 1.9.0 I did this fairly easily by putting them in a R folder, creating a DESCRIPTION & TITLE file etc. I could then load my library successfully. Under R 2.0.0 this simple process apparently no longer works. I have used package.skeleton() and have run R CMD INSTALL pkgname but still get various

A naive question: what happened to the xlsReadWrite package? http://cran.r-project.org/web/packages/xlsReadWrite/ It says that it was removed from the CRAN repository. Are there any plans for it be available again? Thanks, Andrew [[alternative HTML version deleted]]

Hi, I have been using R under Windows but have started to use R (ver. 2.3.0,) under Linux (linux-gnu). I have been saving my workspace and I notice that I sometimes end up with 2 version of the .RData file: .RData and .Rdata. Can someone explain what is happening? I am not sure which one is loaded so I have ended up losing data by deleting the wrong file. I think the saved file should be

Hello, I have a multi-year dataset (see below) with date, a data value and a flag for the data value. I want to find the monthly median for each month in this dataset and then plot it. If anyone has suggestions they would be greatly apperciated. It should be noted that there are some dates with no values and they should be removed. Thanks Emily > print ( str(data$flow$daily) )

Dear R users, When I run the code below, I get the error "Error in integrate(integrand, 0, Inf) : non-finite function value". The code works if the function returns only "sum(integ)". However, I want to add "cmh" to it. When I add "cmh" I get that error. I can't figure out why this is happening because my integrate function has nothing to do with

First, thanks very much for making rmate available. I'm having trouble porting it to e-texteditor for windows, though, (specifically the send-line command) because osascript is mac-only. Is there a way to send selections in e-texteditor to the windows version of R.app? Thanks! Dan
