Hello, I am a bit over my head on this issue. My colleagues and I are running R off of our server. We all have admin rights and prior to yesterday we all had our own libraries. Our main system administrator advised us that we should have a shared library. So, I am trying to do this. I have downloaded the latest version of R and installed it on the main drive of our server in the "Program

Hello help, I have changed around some graphing code and made it into a function. Previously they y label of the axis was inserted as text in its own layout box. text(1,1, expression(~degree~C),cex=1) This worked great and resulted in the symbol for degree. In the function, I have changed it so: text(1,1,paste(b_unit),cex=1) and b_unit<-expression(~degree~C) This now inserts ~degree~C

Hello and thanks for helping. #some data L3 <- LETTERS[1:3] dat1 <- data.frame(cbind(x=1, y=rep(1:3,2), fac=sample(L3, 6, replace=TRUE))) #When x==1 and y==1 I want to replace the 1 values with NA #I can select the rows I want: dat2<-subset(dat1,x==1 & y==1) #replace the 1 with NA dat2$x<-rep(NA,nrow(dat2) dat2$y<-rep(NA,nrow(dat2) #select the other rows and rbind

Hello, I am trying to use R to download a bunch of .csv files such as: http://biocache.ala.org.au/ws/occurrences/download?q=Banksia+ericifolia I have tried the following and neither work: a<- getURL(" http://biocache.ala.org.au/ws/occurrences/download?q=Banksia+ericifolia") Error in curlPerform(curl = curl, .opts = opts, .encoding = .encoding) : embedded nul in string: and

Hello, I am not sure where to begin with this problem or what to search for in r-help. I just don't know what to call this. If I have 5 columns, the first 2 are the x,y, locations and the last three are variables about those locations. x<-seq(1860,1950,by=10) y<-seq(-290,-200,by=10) ANN<-c(3,0,0,0,1,0,1,1,0,0) CTA<-c(0,1,0,0,0,0,1,0,0,2) GLM<-c(0,0,2,0,0,0,0,1,0,0)

Hello, If I have a dataframe: example(data.frame) zz<-c("aa_bb","bb_cc","cc_dd","dd_ee","ee_ff","ff_gg","gg_hh","ii_jj","jj_kk","kk_ll") ddd <- cbind(dd, group = zz) and I want to divide the column named group by the "_", how would I do this? so instead of the first row being x

Hello, I am trying to cycle through a csv and make some summary statistics. I need to select rows based on the number in the row name that comes after the letter 'y'. For example, ? BA1y1 would equal 1, ?C3A2r3y1 would equal 1 and ?MA3r3y1r3 would equal 1. I currently have my code ?cycling through by the 5th character but my rows have variable length and the y can occur in several

Dear List, I am making a list of all the files in a folder and I want to exclude one file called "proj.current". This is the 31st file in a folder. Currently I use the command: tdirs <- list.files(pattern="proj.")[-31] However I would like to exclude it based on its name and not the position. Any advice would be useful. Thanks, Daisy Daisy Englert Duursma Room

Hello, I am struggling with computing nodes in Unix. I have the use of a Unix server that has 30 nodes and I would like to batch scripts. Here is an R example that results in 72 repeated tasks based on the 2 loops. If I wanted to send these out to the different nodes, each node has 1 task and the remaining 42 tasks are put in a queue, what would I do? #Example:

random selection of cells in raster based on distance from xy locations Hi, I am trying to sample a raster for random cells that occur within a specific distance of point locations. I have successfully found multiple ways of doing this but have memory issues with very large datasets. To overcome this problem I am working with lists. I am now stuck on how to randomlly sample the correct elements

Hello, I think this is a simple problem but I am not coming up with a simple solution. I think it just an indexing problem. I can easily replace values in a matrix from a dataframe when the dataframe has row and column numbers. In the example below I use row and column names and I can not get it to work #make a matrix where rows and columns are the lat and long for a bounding box of Australia

Dear List, I am using the command plot to present the relationship between bird richness (Y axis) and elevation (X axis). However, I would like to observe the distributions of bird richness in different administrative areas (A, B, C, …., G) in this plot. For example, the dots in area A might fall in the upper right part of the plot, while those in area B might appear in the middle of

I'm using Ubuntu 8.10 (Intrepid Ibex) and R 2.7.1. I've built a package from source (a modified version of gbm) and it contains some C++ code. I now want to cross-compile it to get a Windows version. I installed R using sudo apt-get update sudo apt-get install r-base sudo apt-get install r-base-dev So far as I can tell, I've also followed all the instructions in the guide

hi, I have two private packages, the first (`pkc') depending on the second one (`roiutils'). The source code and DESCRIPTION files describes the dependency as it should be ('Imports', `require'), at least I think so. now, running R CMD CHECK pkc yields the following output in which I have inserted my questions (lines starting with -->): * checking for working latex ...

I tried two times to get some help for this from the help list but to no avail. I hope, it's OK to post this here (once...). if not, please ignore (the rest of) this mail: for one of my private packages R CMD CHECK {package} givves me annoying warnings due to 'missing links' in the manpages for functions from another private package mentioned in the manpages. specifically, I have two

Hello, I have two plots on the same screen. I use the command par(mfrow=c(1,2)) in order to do this. When I try to make a legend for both plots, it only puts the legend in the plot on the right side. If I would like a legend that is outside of both of the plots, how would I do this? Thanks [[alternative HTML version deleted]]

Hey guys, I've search a few threads about deleting a value from a vector, but no one has addressed this question so far. I want to delete the last value from a string of values I have: r = [ 1, 2, 3, 4, 5 ], and i want to make r2 = to [ 1, 2, 3, 4] So that r2 is just like r, except that it missing the final value.

When I installed RSRuby (Ruby interface to the R programming language), an error occured : cannot find the R library. I defined Rlibrary : R\library in PATH on Windows but it didn't work with the same error. RSRuby ask R to permit the option 'shared library' but when I install R, it didn't ask me for this option. I want to ask you how to share le library in R? And when I can find
