Hi, I am troubled by the use of NULL or NA to indicate missing/non-specified function arguments. In the R code that I have looked at, it seems that both forms are used (NULL seems to be used more often though). Sometimes both variants are in the same declaration, e.g. format.default <- function(x, trim = FALSE, digits = NULL, nsmall = 0, justify = c("left",

Hi, On windows I'd like to run a batchfile that leaves me a plot. As a test I have the scriptfile "test.r" which only contains: x <- 1:10; y <- sample( 10 ) plot( x, y ) Now I tried the following (but nothing worked): a) "R --vanilla < test.r" in the cmd window, => that doesn't give me a plot b) the same, but I added

Hi, I try to delete the files in a directory. While the command invisible(lapply( list.files( "DeleteThis" ), function(x) file.remove(paste("DeleteThis", x, sep="/" )) )) works, I keep thinking that there should be a more direct command. "unlink" looks like a good candidate but whith this I only arrive to either delete the whole directory or nothing

Dear R-List, I've written some code to put measurement values at a position x and y in bins (xb and yb). It works, but I wonder if there isn't a function that would do what I do by hand in "# fill data in bins"? Here is the code: # data x <- c( 1.1, 1.5, 2.3, 2.5, 2.6, 2.9, 3.3, 3.5 ) y <- c( 6.3, 6.2, 5.9, 5.3, 5.4, 4.2, 4.8, 4.6 ) val <- c( 50, 58, 32, 14, 12,

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 ),

Hello! I (try to) convert the external R header files to Pascal (Delphi). At one place I stumbled over a macro that uses a method that is not declared in a LGPL header file: In Rinternals.h: #define error_return(msg) { Rf_error(msg); return R_NilValue; } #define errorcall_return(cl,msg){ Rf_errorcall(cl, msg); return R_NilValue; } ~~~~~~~~

Dear list members, I have written a function, called say Analysis. I supply an Excel file name as an argument, it does analysis on this file and returns a pdf file with specific plots, and a text file with several statistical models' output (I extract certain values from the output and create my own custom dataframe with output). As of now I have to open the script file and load the function

Hi, I execute the following code snippet.What I don't understand is, that in the first two cases the numbers shown don't correnspondant to the input (though I have set the options to show 22 digits). When I assign the third number which has one place, the display of the numbers is suddenly correct. Can anybody explain what happens here? (this is just a sample, my real problem lies in

Dear R-Users, I have two questions: a) in a directory there are 3 files: [1] "Data.~csv" "Kopie von Data.~csv" "VorlageTradefile.csv" The command "dir( fold, pattern = "\.csv" )" gives back *all* the 3 files With dir( fold, pattern = "\\.csv" ) I get back only VorlageTradefile.csv. I don't understand this behaviour,

Hello! I have no problem reading Excel files (each worksheet in the file is a "table" which can be read - at least in my case). What I would like to do is to read such a table, change it (just the contents, not the format) and write it back, and this I can not do. I am getting the following error messages (3 slightly different attempts): > sqlSave(con, x, tablename =

Hi, I want to buy the books "Modern applied Statistics with S" and "S Programming". Both are Springer books and according to the "Discount Info" on the page books related to R (http://www.r-project.org/doc/bib/R-books.html) subject to a 20 % discount. Unfortunatley the promotion code doesn't work. I already contacted Springer but didn't get an answer. Does

Dear UseRs, I have an update ready for the xlsReadWrite package. It runs my unit tests just fine but there are quite a lot of changes and it would be good if some other people could try it out before it will be submited to CRAN. I won't have more time this week, but I hope to publish xlsReadWrite at the end of next week and I will incorporate eventual bugreports and/or (minor) suggestions
