I hope that somebody can help me with this - I think very simple - issue...? I am running a package that only accepts one line at a time, but I would like to run this package on a dataframe of >500 lines. Dataframe "d" is a single column: APPLES PEARS AUBERGINES KUMQUATS I would like to read one line of my dataframe "d", individually into a new frame "f", then

Hi all, I'm trying to find something like the "==" operator that will work on vectors or something equivalent to SQL's "IN" function. For e.g., if I have: x <- c(1,2,3,4,5) y <- c("apples", "oranges", "grapes", "bananas", "pears") z <- data.frame (x,y) w <- c(2,4,5) I want R to return the values

Dear All, I have come across a very surprising result as I have started to learn how to use R to pull data from the web for analysis. I am trying to isolate that table headers for the quarterly income statement (qtrinc) that I pulled from Google finance. I executed the following commands after installing the scrapeR package. require(scrapeR)

I have a file like this: id n1 n2 n3 n4 n5 n6 1 3 4 7 8 10 2 2 4 1 2 4 3 10 3 7 0 0 0 0 8 4 10 1 0 0 2 3 5 11 1 0 0 0 5 what I want to do is: only if n2=0 and n3=0 and n4=0 and n5=0 then delete the row. how can I do that? thank you, karena -- View this message

Hi Reid, I guess it's not so much a memory leak, as unexpected behaviour, resulting in excessive memory use. I also call the following after EE->runFunction, which seems to clean up pretty nicely. EE->freeMachineCodeForFunction(stub); // Delete functions and IR. stub->deleteBody(); stub->eraseFromParent(); Rob. -----Original Message----- From: reid.kleckner at

Dear R users, I was wondering if R has a built-in function doing the following : my_match(values_vector,lookup_vector) { for each value of values_vector : if value %in% lookup_vector, then value is unchanged else, value is changed the the closest element of lookup_vector, "closest" meaning "the one that would come just after if we sorted them using order()" } For example :

I'm unfamiliar with the leak you've just described, but Jeffrey Yasskin has done a lot of work cleaning up leaks for 2.7 and trunk. I was just going to mention that unless the function you are calling via runFunction has a simple prototype that's special cased in runFunction, it will generate its own stub function for every call. If you don't want to worry about that, you can call

Hi all, I am working on my Master's project in security and I am trying to iterate over the argument list of the function. Basically I need to do following things : 1. Check data type of each argument of the argument list of the function. 2. Based on its data type like character array or integer array, pointer, int, char, take different action. 3. I have added following code to check its

Hi all, I have a very simple problem that I cannot seem to find the answer to. Consider the following toy dataset: x <- read.table(textConnection("V1 apples bananas cherries indv.1 7 8 4 3 indv.2 7 7 4 9"), header = TRUE) How would I change the column name of ONLY the first column, not the others? Surely I should not have to re-specify the names of ALL the columns -- e.g.,

Hello, after dealing with shared folder within version 2.0 rc* I started using it with a group of users. user1 shares a folder to user2. user2 has access to messages of this shared folder. After a "random" time (minutes up to several days) user2 doesn't see those messages anymore. user1 (the owner) hasn't changed anything inside this folder. All messages are still in place

Hi, What determines the order of the rows in a barchart? Cheers, Geoff. Here is my code, and the data follows. If I have z in alpha order, the barchart is in some order I can't determine. I originally tried rownames(twater)~twater$Cat, but the chart wasn't in rownames(twater) order either. library(lattice) twater<-read.csv("totalwater.csv",strip.white=T)
