Hi, I have a data.frame that contains a variable act which records the duration (in seconds) of two states (wet-dry) for several individuals (identified by Ring) over a period of time. Since I want to work with daytime (i.e. from sunrise till sunset) and night time (i.e. from sunset till next sunrise), I have to split act from time[i] till sunset and from sunset until time[i+1], and from time[k]

Hi,   I have a dataset which contains several time records for a number of days, plus a variable (light) that allows to determine night time (lihgt= 0) and daytime (light> 0). I need to obtain get dusk time and dawn time for each day and place them in two columns. This is the starting point (d): day time light 1     1       20 1     12     10 1     11     6 1     9       0 1     6       0

Hello, ? I have to create a new column from the values of other columns of a data frame. The new?column (y$n) is created imposing a condition (using a third variable y$h) that assigns the values of two time variables (y$b and y$timepos). Here's the piece of code to get there (using the attached files): ? xact <- read.table("act.lig", sep = ',',

Hello, I'm having problems working with date values in POSIXct format. Here is what I got (eg.lig attached): x <- read.table("eg.txt", sep = ',', col.names=c("ok","time","secs","lig")) # it gives time as factor z <- cbind(x,colsplit(x$time, split="\\s", names=c("date", "clock")))

Dear R list, I have an event history data set that is structured like this: Legislative act Discussion Agreement Time Event Act1 2006-05-30 2006-06-19 20 1 Act2 2004-03-01 2004-06-14 105 1 . . .

Hi Adam, I hope this is what you wanted: dat1<- read.csv("example.csv",sep="\t",stringsAsFactors=FALSE) ?str(dat1) #'data.frame':??? 102 obs. of? 5 variables: # $ species? : chr? "B. barbastrellus" "E. nilssonii" "H. savii" "M. alcathoe" ... # $ period?? : chr? "dusk" "dusk" "dusk"

Hi, I'm trying to make a partial plot with package randomForest in R. After I perform my random forest object I type partialPlot(data.rforest, pred.data=act2, x.var=centroid, "C") where data.rforest is my randomforest object, act2 is the original dataset, centroid is one of the predictor and C is one of the classes in my response variable. Whatever predictor or response class I

Hi all, One of the centos 5.1 servers was scanned by a customer and he suggests turning off daytime on port 13. When I look at /etc/xinetd.d/daytime* the 2 files say disabled yes So is there something else I should be looking at ? Thanks, Jerry

Hello folks, I have this really strange routing problem that no amount of googling and experimenting has been able to solve.

Hi David, Thanks for your answer. Just to clarify, I would like to create 2 3 instructions put them in a function and execute them. Do you still think the JIT would be the best option?

Hello, I'm trying to import into R files that contain data downloaded from logger devices as files with the following formats: .act .lig .trj .trn These files are essentially text files but use both tabs and commas as separators. I've tried the function scan: 1) scan("filename.act", what=character(0)) returns only two columns from the original 5 2) scan("copia.act",

Hi, I posted the following message to the RedHat linux list to see if anyone had any thoughts about this problem. I have only received a few replies, all of which state that they have experinced poor performance problems with ssh on Solaris. They do not, however, state if it is openssh, which version, what hardware, or what version of Solaris. (All I can say is that we have had no problems with

Hey Everybody, I'm trying to use rsync to do a remote backup. First I open a ssh tunnel to the rsync daemon on the server. Then I run rsync through this tunnel. An example follows: ssh -v -x -p 1999 -L 8730:localhost:873 user@host.mydomain.com -f sleep 5 && rsync --port 8730 --verbose --update --archive --exclude='[Cc]ache' --delete-excluded --password-file

For some reason that I have not yet been able to figure out, these tests run significantly more slowly when I run them during the daytime, which I did for that run. I checked a few of the worst regressions reported here and they all recovered in subsequent runs. here is a crazy
