Hi, I am in the process of linking a C/C++ application to the R.dll directly. I have obtained the R source code and compiled it successfully. I have also successfully linked the R.dll directly into our application and have made calls successfully into the R.dll that are included in the sample rtest.c and in the "Writing R Extensions - The R API". The R functionality that we

All, 1. I will try and make this clear and concise. Please let me know any information that would be helpful in figuring out this problem (I don't know the relevant information to post). I am on linux- see below for session information. 2. Problem: working directory: home an old version of a function is sourced into the R session and doesn't work working directory: Desktop the

Hi, I have a data matrix in which there are 1000 rows by 30 columns. The first column of each row is a numeric indicating the number of trips taken to a particular location with location attributes in the following column entries for that row. I want to repeat each row based on the number of trips taken (as indicated by the number in the first column)...i.e., if 1,1 indicates 4 trips, I want

I have a string of binary values, and I would like to flip certain bits in a set of positions. Let's say the vector p contains position [1, 3, 5, 7] vector b contains bits [1, 0, 1, 0, 1, 0, 1, 0, 1, 0] result r should be [0, 1, 0, 0, 0, 0, 0, 0, 1, 0] in pseudo code this would be something like --- r = c() for (i in 1:10) if (i in p) r = c(r, flip[i]) r ----

hello, i try to plot 3 graphs which have the same x.axis underneath each other. i'd like the plots to be aligned without margings between the boxes and draw a single x axis beneath the lowest plot. i managed to get the alignment by setting par(mar), but the middle box is stretched and i cant't figure out how to get around this. par(pin) was my guess, but this doesn't do the job

Hi, Is there a concise/ruby way to do the following: [Note: 1 and 2 below are not related.] (1) for p in 0...@order.line_items[k].shipment_lines.length shipline_qty = shipline_qty + @order.line_items[k].shipment_lines[p].quantity end (2) ts = Array.new for tk in s.trackings ts.push(tk) end

Dear R listers, I am trying to produce a simple (for a stata user) barplot with 4 countries on the x axis, each country observed in 2 subsequent years and 3 variables. Basically, I should have three bars for each year for each country. I am attaching the chart I made in Stata, but I am not sure you'll manage to see it! I did the following: #here I create the data-set TUSE2. The vectors mw, st

# This is more about trying to find a more effecient way to code some simple vectorized computations using ifelse(). # Say you have some vector representing a factor with a number of levels (6 in this case), representing the location that samples were collected.

Dear R people, I have a simple question to ask. Suppose I have a data.frame with two variables: one factor (x) and one numeric (y), I want to calculate the mean of y for each value of x. Although it's easy to do it within a for a loop, I believe there may be a concise way by using some kinds of "apply" functions. Could anyone tell me how to do that? Thank you. Frank

In fs/ocfs2/dlmglue.c:ocfs2_cluster_lock(), after label 'out:' the code is: 1373 if (wait && arg_flags & OCFS2_LOCK_NONBLOCK && 1374 mw.mw_mask & (OCFS2_LOCK_BUSY|OCFS2_LOCK_BLOCKED)) { 1375 wait = 0; 1376 if (lockres_remove_mask_waiter(lockres, &mw)) 1377 ret = -EAGAIN; 1378

That seems mostly reasonable. I'd try to make it more concise, though. The coding standards and developer policy docs should be short. +Commit message +-------------- + +Although we don't enforce the format of commit messages, there are general +guidelines that will help review, search in logs, email formatting and so on. +Mostly, the rules that apply are similar to other git

hello I tried to use lars() but neither with my own data nor with the sample data it works. I get in both cases the following error prompt: > data(diabetes) > par(mfrow=c(2,2)) > attach(diabetes) > x<-lars(x,y) Error in one %*% x : requires numeric matrix/vector arguments > x<-lars(x,y, type="lasso") Error in one %*% x : requires numeric matrix/vector arguments

Hello! I want to create a messagebox whenever the user wants to destroy the window (e.g. <Alt-F4> or the 'x' in the right top corner) and ask if a modified file should be saved or not. If 'cancel' is chosen then nothing should happen and the windows still should be existing. This doesn't work. When I press cancel the window will be destroyed although. I also
