For example, based on a certain condition, I may want to exit my code early: # Are there the same number of assets in "prices" and "positions"? if (nAssetPositions != nAssetPrices) { cat("Different number of assets! \n\n") <exit function> } I have searched, but not

I am trying to change the number format shown on the y-axis from scientific 5e05, to 500,000 etc. Does anyone know how to do this? Is there something I can add as an argument to barplot, or would it be through par? barplot(data$Value, names.arg = as.vector(data$Field), main=strTitle) [[alternative HTML version deleted]]

Hi all, I would like to generate nicely formatted reports on a daily basis. The reports would be a combination of charts and tables, generated in an environment such as R. Ideally, this would be an automated process. Does anyone know if this is feasible, and how I could achieve well formatted reports? One idea would be to have R scripts process the data/generate the charts and then use

Using a more stable nonlinear modeling tool will also help, but key is to get the periodicity right. y=c(16.82, 16.72, 16.63, 16.47, 16.84, 16.25, 16.15, 16.83, 17.41, 17.67, 17.62, 17.81, 17.91, 17.85, 17.70, 17.67, 17.45, 17.58, 16.99, 17.10) t=c(7, 37, 58, 79, 96, 110, 114, 127, 146, 156, 161, 169, 176, 182, 190, 197, 209, 218, 232, 240) lidata <- data.frame(y=y, t=t) #I use the

I tried both the most recent version of "simple" register allocation and the one from last August, and neither seems to work correctly (they run, but produce bad output). I used them to compile an old version of the Unix "replace" utility (source code attached). Here's how I created the executable: llvm-gcc -emit-llvm -O0 -c replace.c -o replace.bc opt -mem2reg

The following code crashes R (I know I shouldn't try to estimate such a model; this was a bug in some code of mine). I also tried with R-devel; same result. tab <- structure(list(dob_day = c(FALSE, FALSE, FALSE, FALSE, TRUE, TRUE, TRUE, TRUE), dob_mon = c(FALSE, FALSE, TRUE, TRUE, FALSE, FALSE, TRUE, TRUE), dob_year = c(FALSE, TRUE, FALSE, TRUE, FALSE, TRUE, FALSE, TRUE), n =

Hi there, I am wanting to create 8 side-by-side histograms which have been rotated 90 degrees clockwise from how they usually sit.. all with the same scales. Is someone able to help me out?

I've tried Zorrin, Ubuntu and Centos. Zorrin and Ubuntu work fine, but Centos doesn't load, or run. I asked for advice, didn't get any and seem to have been added to all your Centos mailing lists.

I am wanting to create a model matrix and keep the NAs. stratmat <- model.matrix(myformula,mydata) Is there any way to do this? model.matrix doesn't have na.action as a parameter.

Hi there Probably a very simple solution to this problem.

I found the problem! My generated code is spilling correctly but is not reloading at all. For example, if the original code has the equivalent of this (where %1024 is a virtual reg): %1024 = xxx ... yyy = %1024 and I find no physical register for %1024, then I assign it to physical register %edi and to a stackslot. That creates code like this: %edi = xxx store from %edi to the

Hi Just noticed that the windows() function doesn't seem to allow for decimals in the width and height options. For example, typing: > windows(5,4,10) > windows(5.2,4,10) > windows(5.4,4.3,10) produces three equally sized windows. Is there a way to get around this and create more accurately sized windows without having to resize by hand? Thanks Rachel Cunliffe Department of

Hello R experts I am using Hmisc aregImpute and Impute (following example on page 105 of The Hmisc and Design Libraries). *My end goal is to have NAs physically replaced in my dataframe.

Since some of you use the jailutils package, I just wanted to post some additional info on the recent 'security fix' and also highlight a possible issue with the 'jail' command. http://memberwebs.com/nielsen/freebsd/jails/jailutils/security.html It's not a very big issue (unless I'm missing something), simply one of leaking the host environment into the jail.

Hi there, I've spent a while searching for ways of outputting table data from R in presentable formats, such as colored backgrounds for column headings, bold fonts etc. It appears that this is not possible, but I would be interested to learn if in fact there was a way of achieving this. Many thanks! [[alternative HTML version deleted]]
