I have to load 10 different data frames and then manipulate those 10 data frames but would like to do this in a more simplified code than what i am doing. I have tried a couple of approaches but cannot get it to work correctly. So the initial (bulky) code is: #Bin 1 #------- #Loads bin data frame from csv files with acres and TAZ data Bin1_main <-

Dear All, I created a script to calculate averages - two groups: "parcel" and "date" - and, based on these averages, make a graph. The problem is that 'R' does not recognize the first column even if I try to insert one. A brief example Raw data: Data <- sample(1:100, 30, replace = FALSE, prob = NULL) Date <-

I am trying to simplify my code by adding a for loop that will load and compute a sequence of code 10 time. They way i run it now is that the same 8 lines of code are basically reproduced 10 times. I would like to replace the numeric value in the code (e.g. Bin1, Bin2....Bin10) each time the loop goes around. Below i tried doing this with a simple for loop and adding the string character before

Dear All, I have tried to calculate tree mean growth but I think the structure I used below (growthresumo) is not the most elegant, even though it worked. The only problem I had in this first part was that I cannot use 'summary', just 'mean' (sorry but 'R' is pretty new for me). >growthresumo <-

Statement 9 using sapply does not seem to give the correct answer (or at least to me). Yet I do what I think is the same thing with statement 11 and I get the answer I'm looking for. 9 : s <-sapply(unlist(v[c(1:length(v))]), max) 11: for(i in 1 :length(v)) v1[i] <- max(unlist(v[i])) Shouldn't I get the same answer ? library(XML) rm(list=ls()) url <-

I used screen scraping to extract some information and put it into a table called tbl. Now I want to modify the table a bit so the data can be more useful. Here's the code I used: library(XML) rm(list=ls()) url <- "http://webapp.montcopa.org/sherreal/salelist.asp?saledate=05/25/2011" tbl <-data.frame(readHTMLTable(url))[2:405, c(3,5,6,8,9)] names(tbl) <-

Hello, recently I read about the SweaveListingUtils package and now I want to try it out. However, I can not make it work... Below a minimal example. The problem seems to be the following line (generated by SweaveListingPreparations()?): \ifthenelse{\boolean{Sweave@gin}}{\setkeys{Gin}{width=0.6\textwidth}}{}% If I comment out this line, it works. What can I do about this? I am using the

Hello all, I have an Order object that has and belongs to many Products and has and belongs to many Loan Types. This is so I can select multiples of each in my order entry screen via checkbox groups. I''m having some trouble with saving multiple HABTM associations for a single model object; only the first HABTM association declared in the model will save during the initial @order.save

Hello all. I'm setting up a new call center PBX using * v1.4, and figure it's better to go with AddQueueMember over AgentCallbackLogin. The functionality of AgentCallbackLogin still works, but without a firm idea of how long it will be in the codebase, I'm wary of building a system on top of it. The basic mechanics work, but I'm having some trouble on logging. With

First, thanks to Timo for the patch -- fixed missing protocol name error on my Solaris box. Now, I've moved the whole distro, part and parcel, to a Centos 4.0 Linux box, with the HOPE of getting it working there. But when I've set all of it up, I get the error message, mentioned in the 'Subject' line, in my /var/log/dovecot file. Any clues? PEV

I am making frequency histograms using the histbackback function on my 2 datasets. However when I try to use the brks function: foo<-histbackback(log(fie11), log(fie86),ylim=c(0,9),probability=FALSE,axes=TRUE,ylab=("log10 Parcel Size"),brks=16) The graphic results in a 'NA' label for the y axis (no intervals are returned) Also when I use 'summary(foo)' the

Hi, all. I'm running R on a beowulf system, with software that can take a list of single-processor jobs and parcel them out over the system. (In case it's of interest, they're dual pentium 866 machines connected by fast ethernet.) The administrators of the system found that I was causing a huge load on the file server, and when they investigated it turned out that each process was

Can't seem to get the code below working. It gets stuck on line 24 inside the function hm; comments show the line in question. The function hm is called by sapply and is at the bottom of the code. Other stuff above line 24 works correctly including the first couple of lines of the function hm. Should I be using a different apply function or am I doing something wrong with xmlTreeParse ?

Agreed, I too was wondering why we need both arrays and vectors. It goes against the grain, I think, of the structure typing system used by LLVM. For example, a vector of 4 floats and an array of 4 floats are structurally the same type. Would it be feasible in the future to consolidate the two types by allowing "vector" operations (add, multiply, etc.) on arrays where it makes

Hello all, I am wondering if there is a way to do a spatial error probit/logit model in R? I can't seem to find it in any of the packages. I can do it in MATLAB with Gibbs sampling, but would like to confirm the results. Ideally I would like to use this model to predict probability of parcel conversion in a future time period. This seems especially difficult in a binary outcome model

Hi everyone, I have a problem with my Puppet server, the server is overloaded and processes need to add half of my farm nodes yet!

Hi: First my apologies for cross-posting. A few days back I posted my queries ar R-sig-geo but did not get any response. Hence this post. I am working on two parcel-level housing dataset to estimate the impact of various variables on home sale prices. I created the spatial weight metrics in ArcGIS 10 using sale year of four nearest houses to assign weights.  Next, I ran LM tests and then ran

Dear R-people, I hope asking this is not too cheeky, but I do have a R Problem. I hope that some of you like to play around with R and can help me. Its like this. I have several plant species (A,B,C) and 10 replicates per species. 5 plants per species are damaged, 5 not. I let a caterpillar feed on each plant and measured the growth of the caterpillars on control plants (CR) and on damaged

Andrew, your response highlights a naming problem in LLVM, which is that "array" and "vector" mean the same thing in normal computer language and compiler theory usage, so it is inconvenient and misleading within LLVM to give one a very specific meaning that is different from the other.... to the LLVM developers I would suggest using the term
