I have been trying to read a random sample of lines from a file into a data frame using readLines(). The help indicates that readLines() will start from the current line if the connection is open, but presented with a closed connection it will open it, start from the beginning, and close it when finished. In the code that follows I tried to open the file before reading but apparently without

Dear R users, I have been plotting several graphics in only one page. I intend to plot only one legend in each page. Since the graphics are inside a loop I have to do it automatically. The main problem is that inside the loop I work with differente types of variables, I mean , the range is different for each one. I have already tried : par(xpd=TRUE) pos<-par("usr")

Dear R users, How could I managed graphics in GIF format? What I have been doing is graphics in *.ps or *.eps and after I convert them using CONVERT (from ImageMagick) but the output quality is not good. Since these graphics will be use for other users they must have a better image quality. I really appreciate any help, -- Abraço, Nilza Barros [[alternative HTML version deleted]]

Is there any documentation on what kind of SPSS file can and cannot be read by read.spss? Alternatively, how can one modify or "clean" an SPSS file to make it readable by read.spss? What properties must a *.sav file before read.spss can read it? The file in this example is 270KB, with 5 rows and 173 columns. I have no trouble reading larger files with read.spss, so it's not

Dear R-ers, I hope there is a really simple solution to my problem. I've written a function that I saved in an .r file. I source this file in my code. For a while it worked fine. But then when I run the line: source("F mylineplot.r") I started getting a warning: In readLines(file) : incomplete final line found on 'F mylineplot.r' I have no idea why - I tried to check and

Dear R-help community, My main goal of this message is to find a way of skipping a file of a month/year in a loop that does not exist (and making it's output into an data.out array would be NA) and moving onto the next year/month in the loop to carry on filling data.out with real precipitation data. The situation so far: I downloaded 50 years worth of GRIB data files from the NCEP data

Hi Jenny If you want a general solution I understand. However I just downloaded the file fine (as far as I can tell) so you are welcome to have a copy. I can email it to you if you want. I do not think your test for NA is valid. i.e if(test != "NA"){ } I think you should use if(is.na(test)){ } Or something similar. J --- John Seers Institute of Food Research Norwich

Dear R-user, I have to feed my database using some SQL commands. I have already read a data frame with the data I need but after that these data should be write in a file wtih SQL commands. 1) My dataframe: dput(Alldados) structure(list(Station_NO = c(836490, 836920, 836950, 836980, 837380, 837460), TMAX_2M = c("NULL", "NULL", "NULL", "NULL",

Here's how I set up the data for processing: // For moving data into 32 bit shape uint8_t *buffer8 = NULL; uint16_t *buffer16 = NULL; uint32_t *buffer32 = NULL; unsigned sample32; unsigned sample, channel; uint32_t bitsPerSample = this->get_bits_per_sample(); numFrames = inData.GetSize();
