similar to: Creating a sequence from two samples with several constraints (frequency and repeats)

I have a list (length 750), each element containing a vector of unique strings (unique gene ids), with length up to ~40 (median 15). I want to compile a matrix of all possible triplets and their frequency within gene elements. Using combn and a lot of looping, I am accomplishing this but it is VERY slow. I've tried to figure out a way to vectorize this, using "match" and

First, happy holidays, everyone! Thanks to the R team for bringing out 1.4 before the new year. I have 10000 integer triplets stored in A[1:10000, 1:3]. I would like to find the unique triplets among the 10000 ones with possible duplications. What is the easiest way for this. I know the function unique(), which apply to a vector, not the 10000*3 array in my problem. Thanks in advance. Jason

Greetings, After pouring over the documentation for the 'colorspace' package, I have not been able to figure out how the plot() method converts colorspace coordinates to RGB values for display on the screen. I am convert between colorspaces with the various as() methods... but cannot seem to find a way to extract RGB (i.e. for displaying on a computer screen) triplets from color space

This is not an R question, but a question on some combinatorial mathematics. Apologies for the OT if it is wildy inappropriate. The traditional C(n.k) method tells me how many combinations k I can make with n objects. However, suppose I want the number of combinations where an object cannot be used more than Q times where Q is a parameter that changes? For instance: combn(LETTERS[1:5], 3) shows

Is there a way to call Matlab and Gauss code in R? I see functions that work for C/FORTRAN, but not for other languages.

Dear R helpers I have following data stocks <- c("ABC", "DEF", "GHI", "JKL") prices_df <- data.frame(ABC = c(17,24,15,22,16,22,17,22,15,19),                                          DEF = c(22,28,20,20,28,26,29,18,24,21),                                           GHI = c(32,27,32,36,37,37,34,23,25,32),                                          

Hi, this is just a quick question about the list, not about R. I'm trying to filter r-help questions into a separate inbox folder in Outlook Express, but I'm having trouble. All my other filters for lists seem to work except for this one. I've tried just about every email address that it seems the messages come from (starting with r-help). Any suggestions? It's just a matter

I've writen this function (imagenrgb) to display a (m,n,3) array as a RGB image with ngris^3 colors and,optionally, stretching. If option ver=F, it does not display but saves a pseudocolor version of the image as a list (so that subsequent displays are faster). I'd appreciate feedback and improvements and hope that it's useful for others. Example of use: > dim(imatest) [1] 100

Hello - What I want to do seems very simple - I want to make sure any H.323 traffic gets processed before anything else entering or leaving this network. The network has a videoconferencing device on the LAN at 192.168.16.4. A Linux firewall NATs an external IP Address to this internal address and I have appropriate SNAT and DNAT rules that work. The NAT and connection tracking rules all work

Set pv_time_ops.sched_clock to vmware_sched_clock(). It is simplified version of native_sched_clock() without ring buffer of mult/shift/offset triplets and preempt toggling. Since VMware hypervisor provides constant tsc we can use constant mult/shift/offset triplet calculated at boot time. no-vmw-sched-clock kernel parameter is added to switch back to the native_sched_clock() implementation.

This is a seemingly simple problem - hopefully someone can help. Problem: we have two integers. We want (1) all the common factors, and (2) all the possible products of these factors. We know how to get (1), but can't figure out a general way to get (2). Example: 40 and 80 have these factors: c(1,2,2,2,5) and c(1,2,2,2,2,5). We can use match() to get the common factors c(1,2,2,2,5). What

Hello. Is there an easy-to-use contour plot function analogous to scatterplot3d that can draw handle a dataset of arbitrary (x,y,z) triplets? That is, say x, y, and z are each measured quanties, and exhibit neither order nor regularity. I looked at the lattice package function "contourplot" but it seems complicated, and it's not clear from the documentation whether it can

Hi, I'm creating a lot of tables in a file for inclusion in a Latex document. When I try to compile that document there is an error "too many unprocessed floats." Is there a way to correct this? Also, in a Latex table I want R to put in a $\beta$ in the caption, but it puts a weird system character instead of the \b Brian

I am tracking down an x86-64 code generation problem that has to do with AVX instructions. The symptom is: a function is called, and the upper half of the function argument (which is short16) is zero. This happens only when I compile code with pocl, but not when I use clang and/or llc manually. I tracked this down to the following. The call site looks like vmovdqa 24064(%rsp), %ymm0 vmovdqa

I am new to R but am experienced SAS user and I was hoping to get some help on counting the occurrences of a character within a string at a row level. My dataframe, x, is structured as below: Col1 abc/def ghi/jkl/mno I found this code on the board but it counts all occurrences of "/" in the dataframe. chr.pos <- which(unlist(strsplit(x,NULL))=='/') chr.count <-

dear all, I have some very long strings and would like to break up each long string into multiple strings with a fixed length, e.g. to break up abcdefghijkl into abc, def, ghi, jkl I tried a couple of commands but was not successful. Any help will be appreciated. Best, Jimmy -- View this message in context:

Miscellaneous fixes to: - Handling of Ceph drives now works end-to-end (RHBZ#1026688). - In particular, you can now use rbd:/// URIs in guestfish (and they work). - Parse Ceph & NBD network drives from libvirt XML correctly, so that existing domains with Ceph/NBD drives can be added (eg. using guestfish -d option). - Add more testing of the above.
