...le but I''m just having trouble making headway into what is probably a very easy subject. I understand arrays with at least 4 other languages but with Ruby I haven''t found a mental connection with how I can assign variables to arrays.. Take for example: def calculate_tsos(model, datavar, teamvar, valvar) var = model.compiled_this_week.find(:all) var.each_with_index do |rows, i| puts "#{model} [ Row #{i} | Team ID = #{rows.team_id} | Team = #{rows.team.name} | #{datavar} = #{rows.__send__(datavar)}" end end This will give me: TotalOffense [ Row 0 | Team ID =...

...t each target layer contains values s.t. * ? target values v: (v > 0) || is.na(v) * ?i,j: is.na(value(source[i,j])) ? is.na(value(target[i,j])) I also want, for each layer, to plot both the source and the target. My plot code is like plot.layers.for.timestep <- function(source.file, source.datavar, target.datavar, datavar.name, datavar.n.layers, colors, map) { # Get the grid origin, cell sizes, cell centers, etc # ... pdf("compare.source.target.pdf", height=3.5, width=5, pointsize=1) for (i.layer in 1:datavar.n.layers) { # plot the source data # debugging print(p...

...ar all, when trying to replicate John M. Quick's example for correlations between multiple variables posted on: http://rtutorialseries.blogspot.com/2009/11/r-tutorial-series-zero-order.html with R 2.11.0 (GUI 1.33) using my MacBook Pro with OX X 10.5.8 I got the following error message > datavar<-read.csv("dataset_readingTests.csv") > cor(datavar) Error in cor(datavar) : 'x' must be numeric The funny thing is that when I tried to do the same example using R 2.10.1, it worked fine. Any ideas regarding how to solve this problem? Many thanks in advance, Ruben

...ncdf4 users is trying to make it easier (notably for ourselves :-) to write correctly IOAPI-formatted netCDF. Since IOAPI http://www.baronams.com/products/ioapi/ decorates netCDF, one obvious way to do a package=ioapi is to decorate the netCDF API from package=ncdf4. E.g., to add a data variable (datavar) with the additional IOAPI metadata, ioapi::ncvar_add(...) would call ncdf4::ncvar_add(...), then (e.g.--not complete, strictly for illustration) * create global attr=VAR-LIST if it does not already exist * add properly-formatted variable name to VAR-LIST * add properly-formatted attrs longname, u...

...oth in R 2.10 and R 2.11) because there are only numeric values in the matrix and as.matrix(read.table(..)) now converts the values to numeric by default. I couldn't check John M. Quick's site, but I think the problem is that somehow you are loading char string values in your matrix "datavar".

...f this is not possible, if there is another way to accomplish what I want to do. Perhaps, tapply is not the best way to go about getting what I want. if so what would all you strong programmers reccommend instead. I am thinking that perhaps loops may be the only way to go. raoboot <- function (datavar, statavar, weight, nboot, ciqntl, ciqntu) { i <- 1 sdatavar <- sort(datavar) sstratavar <- sort(statavar) sweight <- sort(weight) sdatavarwght <- sdatavar*sweight # stramn <- tapply(sdatavar, sstratavar, mean) meanvect <- rep(0, times = nboot) stratasize <- tapply(sd...

...oto allow reference semantics). Therefore, ISTM, rather than attempting to modify a (copy of a) file in-place, I should instead [copy the bits I want to keep from the source file to the new/target file, read the one data variable I want to modify from the source file, write the one modified datavar to the target file]. (Please correct me if wrong!) * I have a routine that (I believe) does the desired modification of the one datavar. And from reading `help(*ncdf)` and http://www.image.ucar.edu/Software/Netcdf/ I believe (ICBW :-) I understand the definition, get, and put steps that are...
