Hello everyone, I've come up with a problem with using paste() inside apply() that I can't seem to solve. Briefly, if I'm using paste to collapse the rows of a data frame, AND the data frame contains strings with spaces, AND there are NA values in subsequent columns, then paste() introduces spaces. This only happens with that particular combination of data values and commands. I have

I have two dataframes (df) that share a column header ("plot.id"). In the 1st df, "plot.id" records are repeated a variable number of times based on the number of trees monitored within each plot. The 2nd df only has a single record for each "plot.id", and contains a variable named "load" that is collected at the plot-level and is only listed once per plot

I thought some of you might be amused by this. In my non-work time, I'm an avid weaver and teacher of weaving. I'm working on a project involving creating many detailed weaving patterns, so I wrote R code to automate it. Details here: http://stringpage.com/blog/?p=822 If the overlap between R users and avid tablet weavers turns out to be >> 1, I'll polish it up and turn it

Does anyone know if there is an R function that will take a matrix like this jim 1 0 0 0 0 0 jim 0 1 0 0 0 0 jim 0 0 1 0 0 0 bob 1 0 0 0 0 0 bob 0 0 1 0 0 0 harry 0 0 1 0 0 0 harry 0 0 0 1 0 0 harry 0 0 0 0 1 0 harry 0 0 0 0 0 1 and make it like this? (that is, add together rows that have the same name?) jim 1 1 1 0 0 0 bob

Hi, I am trying to get a summary of the counts of different variables for each sample in a matrix of the form "m" below to generate an output as shown. (Ultimately I want to generate a stacked barchart for each sample). I am only able to get the "table" function to work on one sample (column) at a time. Any help appreciated. Thank you Sarah   a<-c("A",

Hello I have setup a mirror script on our network, and I have some problem to preserve ownership of the files transferred. This problem is causing me a bit of headache as this file transfer is for some production file, where if there is not the right permission/ownership the program crashes, and it keep crashing. I am overcoming the problem by defining manually the ownership as

Dear R users, I'm wondering how I can generate an arbitrary number of loops in R. For instance, I can generate two "for" loops to get ICC among any two-way combination among 10 variables. Here is the code n<-10 for (i in 1:(n-1)) { for (j in (i+1):n) { icc(cbind(DATA[,i],DATA[,j])) } } If I need three-way combination, then a code with three "for" loops will be:

Hello, I'm having trouble performing a certain function within R and I was hoping someone might be able to help. I have a matrix (1000x21) that contains whole-number values ranging from 1-7 and I want to replace all entries within this matrix that have a value of 1 with a random number contained within a different dataframe that has 21 rows,1000 columns. I've tried using the if/else

That does clarify for me that you're missing a step: I didn't clearly follow your description at first. corrplot expects a correlation matrix, not your original data. You need to use cor() first. That's pretty clear in the documentation. See for instance the examples: data(mtcars) M <- cor(mtcars) corrplot(M) Sarah On Sat, Mar 17, 2018 at 12:00 PM Shivi Bhatia <shivipmp82 at

Hello, In my simulation I use the try()-function to catch possible errors when fitting models. I run the simulationon a Linux-server using the command " R CMD BATCH nameOfFile.R &". When executing the code as batch-job I get the problem that the execution is halted without giving an error message. But when I run the code interactivly the error is catched by try() as it would

Hello, I'm running the latest version of dovecot on Linux with mbox mailboxes. Everything works fine. So in my dovecot config I have mail_location = mbox:~/mail:INBOX=/var/mail/%u I would like to now change the mail_location for one user in an attempt to slowly migrate to Maildir format. I'm confused how to do this. I'm running shadow passwords: $: doveconf -n passdb passdb {

I need the output to have groups and the probability any given record in that group then has of being in the response class. Just like my email in the beginning i need the output that looks like if A and if B and if C then %77 it will be D. The examples you provided are just simply not similar. They are different and would take interpretation to get what i need. On Apr 14, 2016 1:26 AM,

Since you only have 3 predictors, each categorical with a small number of categories, you can use expand.grid to make a data.frame containing all possible combinations and give that the predict method for your model to get all possible predictions. Something like the following untested code. newdata <- expand.grid( Humidity = levels(Humidity), #(High, Medium,Low)

Hi Sarah, Thank you for your help. I tried using CR1<-as.matrix(CR1) but gives error Error in corrplot(CR1, method = "circle") : The matrix is not in [-1, 1]!. I am using a corrplot library. Please find the reproducible example: dput(head(CR1,10)) structure(c(26L, 46L, 39L, 38L, 47L, 59L, 56L, 61L, 43L, 60L, 78L, 63L, 2L, 58L, 8L, 1L, 1L, 9L, 11L, 2L, 1037500L, 46747L, 346300L,

Just to give closure here, I eventually gave up, built an Ubuntu 9 VMWare image which uses gcc 4.3.2 by default, installed Eclipse Ganymede and various other tools, then built LLVM 2.5 and my own code. It all ran fine. There is clearly something broken in the CentOS gcc43 package. Definitely one to avoid. [s] On Apr 28, 2009, at 5:40 PM, Sarah Thompson wrote: > (My script does both

Hi, I am using R's grep function to find patterns in vectors of strings. The number of patterns I would like to match is 7,700 (of different sizes). I noticed that I get an error message when I do the following: data <- array() for (j in 1:length(x)) { array[j] <- length(grep(paste(patterns[1:7700], collapse = "|"), x[j], value = T)) } When I break this up into 4 chunks of
