Hello. There are so many sound files in /var/lib/asterisk/en. Is there an easy way to let me play back all of them one by one while I am watching CLI to see the current file name?

Dear R colleagues, I am trying to plot some geophysical data as a filled contour on a continent map and so far the guidance from the R-help archives has been invaluable. The only bit that still eludes me is the colour key (legend) coming with filled.contour: I prefer to generate my own colour palette, mainly based on the quantiles of tenths of the data in order to capture the whole range (of

Dear R-helpers, I'm plotting geophysical data in the form of contours using "filled.contour". The display would be much more effective if the areas with negative values could be color coded by -- say -- "cold colors" in the range of blue to green, and conversely the areas with positive values got plotted with "warm colors", from yellow to red. Right now if I use

Hello all, I was checking the newest update of my library before submitting it to CRAN, using R 2.15.0 and Rtools for Windows 215 using Rcmd in the Command Prompt, on my x64 Windows7 laptop. I recently heard that for checking packages for CRAN submission one should use the option --as-cran; previously I was submitting packages, so I was trying that for the first time. The check proceeds fine

I am trying to extract only the winters (defined to be 01-Dec through 28-Feb) of daily data from 1948-2002. There are 90 days in each winter season. I wrote the following code to gather the winter dates into a single vector: DJF <- NULL for(year in 1949:1999) { temp.begin <- strptime(paste("01/12", year-1, sep="/"), "%d/%m/%Y") temp.end <-

Doh! turns out I was using a newer feature of S-PLUS that is not supported in R, or at least was generating the parse error. replace all a = b with a <- b (except in arguments, naturally ...)

Hi everyone, I have written a class with methods that extend generic functions such as as.data.frame or show. When I load this package, I want to ensure that these methods - along with the other functions in the file - are added to R's search path or updated, if necessary. I have made a package using check/build/INSTALL. Will a simple library() call on the package accomplish this? I

Hi! I have been coding a C-program which will read data from the netCDF format (a commonly used file format in the geophysical research community: see Unidata's URL for explanation: http://www.unidata.ucar.edu/packages/netcdf/), and have got to the point where I don't know what the error message mean. The C-program is called nc2r.c. When compiling the code, I get a number of warnings,

Thank you Rui. I ran the following script df1 <- read.table("solar_hour", header = TRUE) df1$date <- as.Date(paste(df1$year, df1$hour), format = "%Y %j", origin = "2012-08-01-0") df2 <- df1[c("date", "IMF", "SWS", "SSN", "Dst", "f10")] head(df1) #To display all the rows print(df2). It gave me this
