Hello, i only got a small problem. i try to create automatic new dataframes, or png?s. the main problem i got is: how can i create automatic a new name for a file (read out by simply "for") - i tried to use "(paste...) but theres an errormessage, about a wrong declination. R told it is as.character, but need as.Real. Should i use another method than "paste"? i tried as

Hey there, I've got a list of lists with matrices: A list with 13 entries (representing years), each of them another list with 12 matrices (representing one month). In each matrix there are as many rows as there are hours in the different months and 2 columns, since two meteorological parameters are measured. What I want to do is to calculate the hourly mean values for each month over the

Hi all, I would like to fit a gamma pdf to my data using the method of RSS (Residual Sum-of-Squares). Here are the data: x <- c(86, 90, 94, 98, 102, 106, 110, 114, 118, 122, 126, 130, 134, 138, 142, 146, 150, 154, 158, 162, 166, 170, 174) y <- c(2, 5, 10, 17, 26, 60, 94, 128, 137, 128, 77, 68, 65, 60, 51, 26, 17, 9, 5, 2, 3, 7, 3) I have typed the following code, using nls method:

First time to post and searched archive for this problem with no clue. My version is 2.5.1. Below is a function to check if a given date is a valid date to a given date function object. It uses try (also tried tryCatch but with same problem). When given an invalid date, I am hoping try will generate en error message which would be picked up by the geterrmessage and thus expecting a false result.

Dear all, in one part of my code I want to sum two vectors element-wise the problem is that either the 1st vector or the 2nd vector always have one or two less elements example of my problem In TotalVector + (datalist2[[1]]$dataset$Results[[j]]$Results[[time]]$Sweep) :   Länge des längeren Objektes          ist kein Vielfaches der Länge des kürzeren Objektes Browse[1]> str(TotalVector)  int

Hi R-helpers, I am using rpart package for decision tree using R.We are invoking R environment through JRI from our java application.Hence, the result of R command is returned in REXP and we use geterrMessage() to retrieve the error. When we execute the following command, cnr_model<-rpart(as.factor(Species)~Sepal Length+Sepal Width+Petal Length, method="class",

Dear all, I am new R user and I am sure that this question has been asked quite often and I have also googled it and read about it! I understood that in order to read excel sheet into R you need to open it and saved it as csv or text, is this true? or you can use read.delim2 and read.csv2 to do this without the following error > dat <- read.csv2(file="C:\\Dokumente und

Compiling this little function gets me some strange behaviour .initDataDir <- function(){ if(file.exists(LOCATION)) { if(as.logical(file.info(LOCATION)["isdir"]))return stop(LOCATION, " exists but is not a directory") } Z <- dir.create(LOCATION) if(!Z){ stop(geterrmessage()) ## stop("Juggel") } return(Z) } > .initDataDir <-

R 3.4.3 OS X Colleagues I have a 20K line script in which I encounter an unexpected problem. If the script detects presence of a particular file USERCODE.txt, it executes: source(?USERCODE.txt?) If that file is not present, the script executes without a problem. There might be syntax errors in USERCODE.txt; therefore, the code above is embedded in a try command:

Only the default error handler puts the error message in a buffer where it can be retrieved with geterrmessage. try() replaces the default error handler. Either look at the value returned by try() or use tryCatch with conditionMessage.

Luke Thanks ? I revised the code to: ERRORMESSAGE <- try(source(USERSCRIPTFILE, local=T), silent=T) print(ERRORMESSAGE) now returns: $value [1] 0 $visible [1] FALSE Not clear what to make of that.

Hi, at the R prompt, is it possible to retrieve the last error (as in condition object of class "error")? I'm not asking for geterrmessage(), which only returns the error message (as a character string). I'm basically looking for a .Last.error or .Last.condition, analogously to .Last.value for values, which can be used when it is "too late" (not possible) to go back

Dear All, I'm using "reg.finalizer" in a function that is to be called in R scripts to do some cleanup on success. I have not found a way to run the function only if the script run without errors, so when the exit code is expected to be 0. What I've tried is checking "geterrmessage()", but unfortunately it's not perfect: if an error was handled with eg

Hi, I use the code below to aggregate / cnt my test data. It works fine, but the problem is with my real data (33'000 rows) where the function is really slow (nothing happened in half an hour). Does anybody know of other functions that I could use? Thanks, Hans-Peter -------------- dat <- data.frame( Datum = c( 32586, 32587, 32587, 32625, 32656, 32656, 32656, 32672, 32672, 32699 ),

Dear Listers, can anyone help me, please. Since several days i try to figure out, how to assign values, vectors, functions etc to variables with dynamically generated names inside of functions. Sometimes I succeed, but the success is rather arbitrary, it seems. up to now i don't fully understand, why things like get, assign, <<- etc do sometimes work, and sometimes not. here's one
