I have a new device that takes measurements anywhere from every second, to every 15 minutes (depending on changes). The matrix has a date, time and Y column (Y is the measurement). For three days it is 25,000 rows. How do I average the measurements by every 30 minutes so my matrix is 48 rows per day? I have been working on this and cannot figure out a simple method. Any ideas? Thank you. ----- In

So is there a particular MSVCRT.DLL that I should be using? Any other ideas? Really would like to get this working...

I would like to generate pseudo-random numbers between two numbers using R, up to a given distribution, for instance, rnorm. That is something like rnorm(HowMany,Min,Max,mean,sd) over rnorm(HowMany,mean,sd). I am wondering if dnorm(runif(HowMany, Min, Max), mean, sd) is good. Any idea? Thanks. -james

How can I add an overall plot title to these four plots? I would like to have something that says, "Distribution Comparisons": par(mfrow = c(2, 2)) # Plot 1 plot(rnorm(10),type="l",col="red") title(main = list(paste("Normal"), ????????????????????????? col="black", cex = 1.0)) # Plot 2 plot(rpois(10,

I would like to sum/mean/min a list of lists and numbers to return the related lists. -1+2*c(1,1,0)+2+c(-1,10,-1) returns c(2,13,0) but sum(1,2*c(1,1,0),2,c(-1,10,-1)) returns 15 not a list. Using the suggestions of Gabor Grothendieck, Reduce('+',list(-1,2*c(1,1,0),2,c(-1,10,-1))) returns what we want, c(2,13,0). However, it seems that this way does not work to mean/min. So, how to

hello: I have been reviewin my message slog and have found the following message: Dec 19 06:27:28 server02 kernel: EXT3-fs error (device sd(8,7)) in ext3_new_inode: error 28 What is error 28 and should I be worried about it? Ray Turcotte

I am wondering if you know how to return by function or show in boxplot, the indexes of unusual points, such as, points that are outside the box or in [Q3+1.5IQR,Max]. For example, > boxplot(c(4,rnorm(20),8)) There are 2 unusual points 4 and 8. How to show the indexes of 4 and 8 in the boxplot or return them by function? Thanks, -james

I need to find out what the maximum file size in an ext2/3 file system. It appears from the definition of the ext2_inode structure that since the i_size field is a 32 bit integer that the file would be limited by that. Thanks, Jason

Hi all, I am doing some intensive computation right now. My system is Pentium4 3.20G + 1.0G RAM + WindowsXP + R1.9.1. It seems my computer is very powerful. However, when I do some simple matrix algebra operations based on a matrix (DD) with dimension 5000000 by 2, I found that the consumption of RAM is huge. For example, the command a <- 1 - DD[,2] eats my 100M RAM. Does anyone know how

Hi, I wanted to add a few notes in the wiki on the fastestmirror plugin on how you can add exclude info in the fastestmirror.conf file. This became important because amazingly ucalgary.ca shows up as a fastestmirror for servers I have in both Nevada and New York. However, the mirror is horribly slow for actual downloads and frequently times out. So, I just want to add info on how to add the exclude clause to this page: http://wiki.centos.org/PackageManagement/Yum/FastestMirror...
