Creating the right table from lapply list
Perhaps this toy example will help:
## example data
output <- list(1:5, 1:7, 1:4)
lens <- lapply(output, length)
maxlen <- max(unlist(lens))
outputmod <- lapply(output, function(x, maxl) c(x, rep(NA, maxl-length(x))), maxl=maxlen)
outputmat <- do.call(cbind, outputmod)
write.csv(outputmat, na='')
The idea is to pad the shorter vectors with NA (missing) before converting

Extracting subset from netCDF file using lat/lon and converting into .csv in R

Unexpected values obtained when reading in data using ncdf and ncdf4
Dear R Users,
I am encountering a problem when reading nc files into R using the ncdf and ncdf4 libraries. The nc files are too large to attach an example (but if someone is interested in helping out I could send a file privately via an online drive), but the code is basic:
for(i in 1:length(thesenames[,1])){
data <- nc_open(paste(INDIR, thesenames[i,c("wholename")],

Extracting subset from netCDF file using lat/lon and converting into .csv in R
Two questions:
1. Is the order of the dimensions shown what is shown if you look at str(ncin) - I mean shown at the end where it describes the variable and its dimensions?
2. Is you problem how to subset the netcdf file, how to write to the .csv file, or both?

ncdf4 installation problem: undefined symbol [SEC=UNCLASSIFIED]
Hello,
I'm trying to install ncdf4 on RHEL 5.8, R version 2.15.1.

Commas in formatC
formatC() is great for formatting numbers! But it would be even better if it
could optionally insert commas (or semicolons), e.g.
R> formatC(1234567.89, digits=2, format="f", commas=T)
[1] "1,234,567.89"
Here's a snippet of code that does that, which could more or less just be
inserted into at the end of formatC if any R-core guru were so inclined. "r"

How to embede text into the Ogg stream
Hi Folks,
What is the proper way to embed text stream into the Ogg stream? I need to have text information (lyrics as example) recorded together with the audio. Is there a standard mechanism for that? What is the right way to do it?

How to set parameters constraints in a function?
Dear R list,
I have a function specifying my log-likelihood, and now I need to set the
constraint that *alpha > kappa*, could anyone help me with setting this in
my function?
the function is defined as follows:

ncdf4: Why are NAs converted to _FillValue when saving?
Dear all
I'm a newbie regarding netcdf data. Today I realized that I maybe do not understand some basics of the netcdf. I want to create a *.nc file containing three variables for Switzerland. All data outside of the country are NAs. The third variable is calculated from the first two variables. Basically there is no problem to do that. I copy the file with the data of the first variable,

I would like to ask question related to error output.
