Why when I assign 0 to an element of an integer vector does the type change to numeric? Here is a particularly perplexing example: > v <- 0:10 > v [1] 0 1 2 3 4 5 6 7 8 9 10 > class(v) [1] "integer" > v[1] <- 0 > class(v) [1] "numeric" #!! > -- View this message in context:

Suppose I have an n-diml array A and I want to extract the first "row" -- ie all elements A[1, ...] Interactively if I know 'n' I can write A[1,,,,,] with (n-1) commas. How do I do the same more generally, eg in a script? (I can think of doing this by converting A to a vector then extracting the approp elements then reshaping it to an array, but I wonder if there isn't a

When I do dev.new(), the resulting window comes to the front and grabs the focus. Is there a way to prevent this so I can continue working in other windows while the graphics are being produced?

I've asked about custom sorting before and it appears that -- in terms of a user-defined order -- it can only be done either by defining a custom class or using various tricks with "order" Just wondering if anyone has a clever way to order "vintages" of the form 2002, 2003H1, 2003H2, 2004, 2005Q1, 2005Q2, etc some have H1 or H2, some have Q1,Q2,Q3,Q4, some are just plain

What is the simplest way to extract a matched subexpression? Eg. in perl you can do "hello world" =~ m/hello (.*)/ which would return 1(true) and set $1 to the matched subexpression "world". -- View this message in context: http://n4.nabble.com/regular-expression-submatch-tp1459146p1459146.html Sent from the R help mailing list archive at Nabble.com.

Perhaps this is a common question but I haven't been able to find the answer. I have data with many factors, each taking many values. However, only relatively few combinations appear in the data, ie have nonzero counts, in other words the resulting table is sparse. Say we have 10 factors each with 10 levels. The result of table() would exceed the memory space (on a 32bit machine). Is there

Hello, LLVM IR flattens out the structure with one integer element to i32. Is there any way to disable this? I want to preserve the type information of the structure. I tried compiling the program with O0, it maintains the type for most of the instructions but for all. Regards, Sangeeta -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I have a list of numbers (classified as a list) that contains integer(0) empty vectors. How do I convert those integer(0) into NAs? Thanks [[alternative HTML version deleted]]

When operating in daemon mode, will rsync check to see which file is newer and decide which direction to transfer based on that? Example, We have 2 terminal servers, A and B. I want users to be able to work on either server and have their home directories on both stay in sync. If a user logs into server A and changes files, the server would know to transfer the file from A to B. If they log

Hi, How could we print the frequency table (produced by "table") to an Excel file? Is there an easy way to do so? Thanks, Miao > df <- data.frame(x = 1:3, y = 3:1, z = letters[1:3]) > table(df[,c("y","z")]) z y a b c 1 0 0 1 2 0 1 0 3 1 0 0 > test<-table(df[,c("y","z")]) > as.data.frame(test) y z Freq 1 1 a

Hi jpm miao, You can get CSV files that can be imported into Excel like this: library(prettyR) sink("excel_table1.csv") delim.table(table(df[,c("y","z")])) sink() sink("excel_table2.csv") delim.table(as.data.frame(table(df[,c("y","z")])),label="") sink() sink("excel_table3.csv")

The situation is that I know there is a function and know approximately what the name is, and want to find the exact name. Is there a way of searching for near-matches (similar to unix apropos). For example, I know there is a function called something like allequal (or allequals or AllEquals or...). But ?allequal, etc, return nothing, only if I remember the name can I get help via ?all.equal.

I am looking for other option to write the output of the print command in R I am using sink() to write the R output to a file. This is similar to what I have: > a=c(1:30) > a [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 > sink("vectorA.txt");print(a);sink() I am looking for othe roptions to save the output of the print()

Dear R-helpers, I have split a dataframe into a list with five elements, with the following code: > datalist<-split(data,data$UNIT) I would now like to run some code (below) on each element of the list to extract rows from the list elements; then I would like to rbind the extracted rows into a new dataframe containing all of the extracted rows from all of the list elements. I don't

Catching up on post-holiday emails. I may have comments on the more general stuff later, but wanted to respond to this bit more quickly.

I'm sure I'm missing something obvious but I'm not seeing how to simply "vectorize" a function of two or more variables. Say I have f <- function(x,y) if (x>0) y else -y Now I have vectors x and y of equal length and I'd like to apply f element-wise. I.e. conceptually z <- f(x,y) where x, y, z are vectors of the same length Some magic involving apply?

Hi, I am using many comment lines like this # a comment line in a script. Is there any way to print comment lines when I use sink() function? Or, are there any plans to include as an option to sink() function in the near future? I would not want to use cat() function as it will look messy in the original script file. Thanks!

I'd like to capture the results of a print() command so that I can put the results in a tktext widget. I know I can redirect the output to a file with sink. I'm looking for something like that, but where I can redirect the output into a variable. Is there a way to do that?
