Just another localization thread
Hey all, I was playing w/ Thomas Fuch''s Localization module (thanks Thomas!), and just realized how hard is to localize an application in Rails :-) The Localization module works nice, but the problem is the error messages. Its not that good to keep the application in [your idiom] and the error messages in english. I saw the other threads about it, specially the ones that recommends

Spatial join – optimizing code
Hi, Few days ago I have asked about spatial join on the minimum distance between 2 sets of points with coordinates and attributes in 2 different data frames. Simon Knapp sent code to do it when calculating distance on a sphere using lat, long coordinates and I've change his code to use Euclidian distances since my data had UTM coordinates. Typically one data frame has around 30 000 points

Memory leak with character arrays?
Hi - When I'm trying to read in a text file into a labeled character array, the memory stamp/footprint of R will exceed 4 gigs or more. I've seen this behavior on Mac OS X, Linux for AMD_64 and X86_64., and the R versions are 2.4, 2.4 and 2.2, respectively. So, it would seem that this is platform and R version independant. The file that I'm reading contains the upstream regions

Interpreting a string as a variable in a column header
This must be a very simple question, but I can't find any information on it elsewhere, sorry. When extracting information from a list using column headers, how do I get R to interpret something as a variable rather than a string? For example: xx$"YAL002" works, but this doesn't: gene <- "YAL002" xx$gene neither do xx$parse(gene) xx$eval(gene)

Trick to replace NA
Dear members, I have a series of values in a vector and some value are missing and replaced with NA. For example: a <- c(27, 25, NA, NA, 24, 26, 27, NA, 26) I would like to replace the NAs with the value taken from the previous value that is non-NA. The output would be in this case: 27 25 25 25 24 26 27 27 26 Now I do that with a for loop, but I try to eliminate all the loops to gain in

Remove attribute from netcdf4 object
Dear all For a model I need to combine several netCDF files into one (which works fine). For better overview I'd like to delete/remove some of the attributes. Is there a simple way doing this? I'm using the package netcdf4, which creates an object of class(nc) = "ncdf4". It seems that for earlier versions of netcdf objects, there was the function att.delete.nc{RNetCDF}. But

How to plot several years data with date information by months?
Hi, all I have a medium sized data, 6 years. Each observation is a case with a date variable, such as '2004-08-02'. Some of the months didn't occur a case. I want to plot the 6 years data by month, and the Y_axis is the freqency of cases for each month, meaning 12*6=72 bars or points in the figure. I though of a method, 1st, using the months function, then ploting. But I need to
