Hi all, I'm porting a library I wrote in S-plus over to R. All but one of the functions work fine. The only one that doesn't is really giving me a headache. I'm admitting defeat. Can anybody help? Object example3 has been read in using read.table. The statement works fine in S-Plus. When I run the same statement in R the column Prefix, which is read in using the as.character

Hi all, I am working for nest box occupancy data for birds and would like to construct a Markov transition matrix, to derive transition probabilities for ALL years of the study (not separate sets of transition probabilities for each time step). The actual dataset I'm working with is 125 boxes over 14 years that can be occupied by 7 different species, though I have provided a slimmed down

If we use the ROCR package to find the accuracy of a classifier pred <- prediction(svm.pred, testset[,2]) perf.acc <- performance(pred,"acc") Do we?find the maximum accuracy?as follows?(is there a simplier way?): > max(perf.acc at x.values[[1]]) Then to find the cutoff point that maximizes the accuracy?do we do the following?(is there a simpler way): > cutoff.list <-

Hi In rtc_set_time, mktime is called to calculate seconds since 1970/01/01, input parameters of mktime are required to be in normal date format. Such as: year=1980, mon=12, day=31, hour=23, min=59, sec=59. However, the current input parameter of mktime is tm->tm_year, and it is the number of years since 1900. (For example, if current time is 2012/12/31, and tm->tm_year is 112). This is

Methods in OCaml which don't take any parameters don't require the dummy unit arg, ie writing: method foo = ... is fine. The reason you might need the unit arg is if you need to create a closure from the method without calling it, for example if you need to use the method in a callback. In lablgtk2 the convention is to use unitless methods if either: the method shouldn't be used

Dear all, I have an ASCII file where records are separated by a blank. I would like to read those data; however, only the data in rows 1, 3, 5, 7, ... are important; the other lines (2,4,6,8,....) contain no useful information for me. So far I used awk/gawk to do it: gawk '{if ((FNR % 2) != 0) {print $0}}' infile.txt > outfile.txt What is the recommended way to accomplish this in R?

Consider I have the following data: AgeRange AgeOfPerson PersonNo FriendsAtYear0 FriendsAtYear1 FriendsAtYear2 FriendsAtYear3 FriendsAtYear4 FriendsAtYear5 10 - 12 11 1 0 1 2 2 3 3 10 - 12 12 2 0 1 2 2 3 3 15 - 18 13 3 1 2 3 4 6 7 15 - 18 14 4 1 3 4 5 7 7 30 - 40 33 5 3 5 5 6 8 9 30 - 40 36 6 4 4 4 4 4 4 I want to plot the number of friends against number of years, as to show how friendships

Hey all, I feel like the solution to this problem should be relatively simple, but for some reason I can't find answers or come up with my own solution. Given the dataframe: (SpA and SpB not important, want to look at distribution of cooccurance for each year) Year SpA SpB Coocc 2000 0 2000 2 2000 1 2001 8 2001 2 2001 0 2001 0 2002 1 2002 2 How can I apply different functions to

I have a piece of code as the one at the bottom, unfortunately since it involves time series from a db it's not easy to give to mailing list a working script. It becomes very slow after few hundred iterations over variable sp (must process several thousands). The Rprof() indicates that the problem is the use of gc(). Can someone indicate what I have to take care of not to call gc() so often?

Hi there I'm working with ncdf data. I have different dataset for 4 runs, 4 seasons and 3 timeslices (48 datasets in total). The datasets have the following dimensions: 96 longitudes, 48 latitudes and 30 time steps. To read all of them in, I wrote the following loop: runs <- c("03","04","05","06") years <- c(1851,1961,2061) seasons <-

Dear CSAG R users, I will be glad if someone can point out what I am doing wrong or not doing at all in this. I am trying to write out netcdf file in R. I have 26 time step but only the first time step is written. For example: >library(ncdf) >path <- '/home/work/' >forecast <- open.ncdf(paste(path,'cam.1980.2005.nc',sep="")) > fore <-

Hi, I have a couple of observations, a question or two, and perhaps a suggestion related to the plotting of density on the y-axis within the hist() function when freq=FALSE. I was using the function and trying to develop an intuitive understanding of what the density is telling me. After reading through this fairly helpful post:

Running under Redhat 7.3 Linux I have installed R Version 1.8.0 (2003-10-08) from a binary download using the rpm manager. Using packageStatus(), I am attempted to upgrade several packages.

Hello all I''ve just installed xen 4.1.1 on my server and was tryoing to tweak xendomains script to work with new xl schema but I can´t get it to save domains. It does start them with some changes I made to it but when I issue service xendomains stop I just get [ OK ] but domains stay running. Has xendomains script been ported to work with 4.1.1 or is there another alternative to it.

a little out of my comfort zone and have practically gotten what I want but awk seems determined to send a message via std error which is problematic and annoying.

Hi, I am new to R community and I have a question on panel configurations in the Trellis package. Particularly, I have the following code: require(lattice) plotTable <- NULL Date <- seq(as.Date("2006-11-01"), as.Date("2009-12-01"), by = 1) nYear <- length(unique(format(Date,"%Y"))) plotTable$Date <- as.Date(paste(unique(format(Date, "%Y-%m")),

Dear List, I have encountered an odd problem that I cannot understand. It stems from the calculation of true and false positives based on two input vectors x and y based on different thresholds of x, extracted using the quantile function. I am in certain cases getting different values of true positives for the same threshold value when the threshold was found under different quantiles (e.g. the
