Hello all, I set 'UDUNITS_PATH' and 'NETCDF_PATH' successfully to my custom places and then % R CMD INSTALL RNetCDF_1.1-3.tar.gz and got this: ... checking for executable suffix... checking for object suffix... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for main in -lnetcdf... yes checking for main in -ludunits...

Hi, I'm newish to R, a recent convert from Matlab... So far I'm impressed, and determined to solve the following problem, which seems like it should be easy: I have a long (millions of points) data series recorded with a datalogger that produced a timestamp in 4 columns: Year, Day of Year, Time in (H)HMM and Seconds. I would like to have R interpret these columns as a time object and have

Hi, I have a dataframe Wash2005, which has daily weather data. I am doing a regression by month as follows: # FM10 Regression by Month # Plot 12 Month of OFM10, FFM10 for(i in 1:12) { Temp <- subset (Wash2005, MM == i) assign( paste('Wash2005FM10', strtrim(month.name[i],3), sep=""),lm(Temp$FM10.1 ~ Temp$FM10)) } Wash2005FM10Jan, Wash2005FM10Feb, etc holds the

hi ,I am writing a soft package based on R. But when I try to read a configure file showed as below. How can I read the parameter in this text file. How can I read the parameter into each variable in this file ? configinfo<-scan(file(configfile),ok=TRUE,n=-1) scan seems need every line have same column ? configinfo <- readLines(configfile,ok=TRUE,n=-1) methodnum <-

Hello. Sorry for this very basic question but I didn't find (of didn't understand) the answer either in the help or in the online guide. I have a string, let's say "hello". I want to know if there is some character in it, let's say an 'o'. I tried > charmatch("o", strstplit("hello","")) but it gives NA (why??) Thinking it may

Hello list, I have the following scenario: f1 <- function(a) { .... # doing things; may need 'a', but does not change 'a'. g <- function(x) { sum(x + a) # Say. Use 'a'; does not change 'a'. } optimize(f = g, lower = 0, upper = 1) } f2 <- function() { b <- runif(100000000000) # Create big object. f1(a

Hello- Sorry, this is a bit of a noob question, but I can't seem to progress it any further. I have two dataframes which contain a series of strings which exactly match. The problem is one has more rows than the other (more cases have been added) and they have been sorted so that they are not in the same order. The smaller dataframe, though, contains in another column which has codes

Inspired by the functions that Barry Rawlingson and Dave Forrest posted for searching Rwiki and R-help archive, I've made up a function that does the search on Prof. Baron's site (Thanks to Prof. Baron's help on setting up the query string!): RSiteSearch <- function(string, restrict="Rhelp", format="long", sortby="score",

First, my site will be down December 27-28 because of a network upgrade at Penn. It will also be down at least one day before that, while I upgrade the operating system. (And another day some time in January because of a planned power outage.) Second, I have replaced the search engine in my R site: http://finzi.psych.upenn.edu/ I am now using Namazu instead of HtDig. The direct link to the

Hello, I am fixing up a system for someone and they did not make a separate partition for /tmp...but I want to make it noexec, nosuid. I came across a site that said I could skip all the mount/unmount and new partition stuff (which would probably include downsizing a lvm to make room for it)... by adding this in fstab /tmp /tmp bind nosuid,noexec,bind 0 0 and then reboot... There is

I feel like an idiot posting this because every language I've ever seen has a string function that trims blanks off strings (off the front or back or both). Ideally, it would process whole data frames/matrices etc but I don't even see one that processes a single string. But I've searched and I don't even see that. There's a strtrim function but it does something completely

Hi All, I am trying to match two character arrays (email lists) using either pmatch(), match() or charmatch() functions. However the function is "missing" some matches due to differences in the cases of some letters between the two arrays. Is there any way to disable case sensitivity or is there an entirely better way to match two character arrays that have identical entries but written

I accidentally discovered 'convert'. It is a command line utility. Changing a file from png to gif works like this convert aaa.png aaa.gif Amazingly simple, powerful and effective. I've since discovered it has an amazing list of options convert --help a manual file:///usr/share/doc/ImageMagick-6.2.8/www/convert.html and a web site http://www.imagemagick.org/ Does anyone

I'm writing wrappers for some functions that change some of the default arguments. I'd rather not list all of the arguments for the low level functions because there are about a dozen wrapper functions, and about 20 arguments to lowlevel. Instead I'm trying something like this: lowlevel <- function(longname = 1) { cat("longname = ", longname, "\n") }

Dear list, I observed two problems that I suppose are generic. First, using 'Rprof' to profile a parallel (based on the package 'parallel') code caused .... Error in unserialize(node$con) : error reading from connection.... Second, on a multicore desktop, I concurrently opened two terminals and ran two separate R sessions, both running (actually identical) parallel code (which

I use Mac, tried to install the package hdf5-1.6. Its configuration script can't find zlib, which apparently exists in my /usr directory. I used R CMD INSTALL --configure-args=--with-hdf5=/sw --configure-args=--with-zlib=/usr hdf5....tar.gz It still can't find zlib. Is this a bug? Any pointer is appreciated. Zepu

I use Mac. I installed R with the download from R-project, so R is in /usr/bin/R. My TclTk library is installed via fink (although I don't remember I intentionally installed it) so libtk8.4.dylib is in /sw/lib. I tried to install the HDF5 package from within R: >install.packages('hdf5') and it failed like this ------- Loading Tcl/Tk interface ... Error in dyn.load(x,

Hello, It's just a strange coincidence that someone posted just very recently a question about matching. I know there are several match function in the base package (such as match, pmatch, charmatch, and the gsub etc) but I can't seem to use them wisely to be able to get what I need. suppose I have the following strings: "tets" "estt" "rtes7"

Dear R-helpers, We marked 6000 leaves from 5 SPECIES - 10 individuals/species - in two different TREATMENTs: a control and a dry-plot from which 50% of incoming precipitation was excluded. We followed those leaves for 42 months and noted the presence and absence at each visit. I then carried out a Cox Harzard model to see differences in leaf mortality between parcels and among species over time:
