I want to find the DOY (Day of Year) of some dates. I think to substract the date 1. January from the data to achive this. Something like: > d <- as.Date("2006-03-13") - as.Date("2006-01-01") +1 > d Time difference of 72 days So far so good. But d is a 'difftime' object. How do I get an Integer value from that? I tried severel things, incuding the

Dear list - Propoerly a beginner question, so bare with my frustration... I tried install the 'shapefiles' package into R 2.4.0 but it seems that the install had little effect... > install.packages(c("shapefiles")) --- Please select a CRAN mirror for use in this session --- trying URL

Dear list I have a large data frame with house prices. Prices have been converted to price per m2, to be able to compare. Prices are spread over almost 10 years, each price is tagged with the year it relates to. I would like to 'normalize' all the prices to, eg. 2010 prices. The data frame looks like this > head(dafP) Y P 1 2004 11199.60 2 2005 15310.10 3 2005 19491.50 4

Simple question... I would like to dump some summries of lm()'s to small seperate text files. I have looked at: print(), but it don't support output to file cat(), but it claims that 'sum1' is a list write, but that just uses cat()... The script goes something like this: ... lmMax <- lm(NUMAMMON ~ YYYY*MM*DD) sum1 <- summary(lmMax) # help needed here... how to dump sum1

Dear List Sorry if this is trivial, but I can't find it in the manual, FAQ or mail list (2002). I just installed R 1.6.0 (2002-10-01) on Linux R.H. 7.2 (2.4.9-32.5) on an DIGITAL AlphaServer 800 5/500 The program starts up nicely but exits immediately with a "Segmentation fault" at the first command. It seems that it doesn't matter what command, I tried q(), help(), version,

Dear list I'm plotting ( boxplot() and plot() ) some data for a publication. The editor would like the text labels on the plots in a larger font. I'm doing something like this: <snip> jpeg( filename = "D:/Martin/Work/CleanPath/RAF1%03d.jpg", width = 1000, height = 600, pointsize = 12, quality = 100, bg = "white", res = 96, restoreConsole = TRUE )

I have a data frame (daf1), that holds +80000 records, and 10 variables (i.e. 10 columns and some 80000 rows) > length(daf1) [1] 10 > length(daf1[,1]) [1] 83805 I would like to sample() e.g. 10000 records from this. I use: > daf2 <- sample(daf1, 1000, replace = FALSE, prob = NULL) Error in `[.data.frame`(x, .Internal(sample(length(x), size, replace, : cannot take a sample larger

I have a monthly price index series x, the related return series y = diff(log(x)) and a POSIXlt date-time variable dp. I would like to apply annual blocks to compute for example annual block maxima and mean of y. When studying the POSIX classes, in the first stage of the learning curve, I computed the maximum drawdown of x: > mdd <- maxdrawdown(x) > max.dd <- mdd$maxdrawdown > from

Dear List I'm trying to run R on a DIGITAL Alpha / Linux RedHat 7.2 The .rpm requires libreadlin.so.4.1 RedHat 7.2 comes with libreadline.so.4.2 I installed the R-1.6.0-1.aplha.rpm with option --nodeps, since it otherwise complained that the required libreadline.so.4.1 was missing. This seemed to be the only unsatisfied dependency, at least that was the only one mentioned when installing

Hi All, In the script below, the importance measure for column 4 (ie MeanDecreaseGini) indicated "Inf" for V7. Running the getTree command showed that "V7" had been selected at least twice in one of the trees for Random Forest. So the "Inf" command was not generated as a result of dividing the sum of the decreases by 0. Any suggestions on what may be causing the

Dear R users, I have a function (simplified here) that accepts two arguments and performs various calculations: foo <- function(y, x) { a <- y*sqrt(x) b <- a+2 c <- a*b return(c) } If I call the function as follows I get the result I desire: > foo(.1, 1:12) [1] 0.2100000 0.3028427 0.3764102 0.4400000 0.4972136 0.5498979 0.5991503 0.6456854 0.6900000 0.7324555 0.7733250

Hi All; I would like to use Asterisk for a call center, but really does not know if Asterisk support the following in a good way: 1) Ability to do an inteligent routing, so to route the call to the proper skill group based on the caller information? 2) If I can create skill groups and then the agent will login to this skill group. 3) What about reporting to check the call center performance?

I''m looking for the most reliable setup for Mongrel. Reliable meaning avoiding things like sending too many requests to a single mongrel process, or sending requests to a mongrel process that has hung for some reason. The handler will most likely be rails, but it might be a custom handler. SSL is also a requirement, which limits the options a bit but it can''t be done away

Hello guys! Sorry to bother with such a question I was trying to generate a monte carlo simulation with heteroskedasticity errors. but I am not sure if the command line that I had wrote is quite correct. the type of heteroskedasticity that I want to create is such as var(e) = var(x^4) I began my work with this x<- rnorm (100, 2,0.4) # generating an indepedent random variable e<-
