Hi R-experts! Every once in a while I need to convert a factor to a vector of numeric values. as.numeric(myfactor) of course returns a nice numeric vector of the indexes of the levels which is usually not what I had in mind: > v <- c(25, 3.78, 16.5, 37, 109) > f <- factor(v) > f [1] 25 3.78 16.5 37 109 Levels: 3.78 16.5 25 37 109 > as.numeric(f) [1] 3 1 2 4 5 > What I

Hello R-experts! When I produce a plot R takes avoids overlapping axis labels in order to maintain readabilty which is great. But now I have written a little custom plot function in which I set my own labels and label positions after generating the actual plot: axis(..., lables=c('A', 'B', 'F', 'G', 'M'), at=mypositions) As you may have guessed: This is

I'd like to make a plot showing frequency of an event. The data is in a data from that includes Year, Month and Day (of month) fields, so I created a Date with ISOdate(Year, Month, Day, tz=''). I can plot frequencies for the year 2002 with > thisyear <- Date[Year==2002] > hist( thisyear, xaxt='n' ) > axis.POSIXct( 1, at=seq(min(thisyear), max(thisyear),

Hi, when trying to configure my samba server, I was curious if there's any Domain controller running on our subnet. I could only find notes in documentation of samba, that there has to be only one Domain Controller running, otherwise weird things would happen ... Btw what are those weird things? I couldn't find an option in smbclient or nmblookup to list for example Domain

Hi, I have the following problem. I think it's arising from the fact, that DES algorithms are fetched from libcrypto and not from libdes anymore. But, some types still clash. I use krb4-1.2.1 from http://www.pdc.kth.se/kth-krb cc -O2 -n32 -TARG:platform=IP22 -OPT:Olimit=0 -I/usr/local/include -I/software/@sys/usr/include -I/usr/local/BerkeleyDB.4.0/include -I/usr/local/openssl/include

Hi, I see some wird messages in samba's logfile on Solaris 2.6. Could anyone explain me what's that? I think some hostanmes and usernames are just missing.

hi, I've troubles with some difftime objects. e.g. ISOdate(2001, 4, 26) - ISOdate(2001, 2, 26) - 2 works, telling me "Time difference of 57 days". But when I'd like to add days, such as ISOdate(2001, 4, 26) - ISOdate(2001, 2, 26) + 2 the function gives me an error. Function "as.COMDate.chron" of the Rbloomberg package doesn't work for that reason. I'm

Hi, I've seen that openssh will have different function names for des, I think thats great. As kerberos4 nor kerbero5 from KTH in Sweden support those new calls yet, I thought it would be best for me to switch back to the old behaviour, i.e. have kerberized libkrb and other libs with disabled support for openssl (which means libdes is compiled). Then, compile openssh-3.5p1 with kerberos4

Dear R-people! I am using R 1.8.0, under Windows XP. While using ISOdate() and strptime(), I noticed the following behaviour when "wrong" arguments (e.g., months>12) are given to these functions: > ISOdate(year=2003,month=2,day=20) #ok [1] "2003-02-20 13:00:00 Westeurop?ische Normalzeit" > ISOdate(year=2003,month=2,day=30) #wrong day, but returns a value [1]

Hi, it seems rsync's configure complains about sys/mode.h. here's the relevant part from config.log. Any idea what should I do now with it?

Hi, I'm unable to get Kerberos4 authentication working with openssh-3.4p1. I'm getting a message that privsep is not available on my platform (Irix 6.5.15) and another message stating that compression and privsep are mutually exclusive. But, ssh decided to turn off compression, I think because of servconf.c. I think it would be more usefull to have compression enabled and disable privsep

Although the documentation is somewhat sketchy, I() can be used to create objects of class AsIs: > I("a") [1] "a" attr(,"class") [1] "AsIs" "character" > I(4) [1] 4 attr(,"class") [1] "AsIs" "numeric" > I(4 + 0i) [1] 4+0i attr(,"class") [1] "AsIs" "complex" > This

Dear all, I have found the following (for me) incomprehensible behaviour of ISOdate (POSIXct): > ISOdate(1900,6,16) [1] "1900-06-15 14:00:00 Westeurop?ische Sommerzeit" > ISOdate(1950,6,16) [1] "1950-06-16 14:00:00 Westeurop?ische Sommerzeit" Note that in the first case I get the 15th of June back, not the 16th as I would have expected! This happened under R-1.7.1 on

Hi, Given a date, how do I get the last date of that month? I have data in the form YYYYMM, that I've read as a date using > x$Date <- as.Date(ISOdate(substr(x$YearEnd,1,4),substr(x$YearEnd,5,6),1)) But this gives the first day of the month. To get the last day of the month, I tried > as.Date(as.yearmon(x$Date,frac=0)) But I don't get the last day of the month here. (Tried

The interface for dates in R is a little confusing to me. I want to create a vector of Date objects from vectors of years, months, and days. One solution I found is: years <- c(1991, 1992) months <- c(1, 10) days <- c(1, 2) dates <- as.Date(ISOdate(years, months, days)) But, in this solution the ISOdate function converts the vectors into characters, which can cause serious

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

Hi Ogbos, You can just use ISOdate. If you pass more values, it will process them: ISOdate(2018,01,22) [1] "2018-01-22 12:00:00 GMT" > ISOdate(2018,01,22,18,17) [1] "2018-01-22 18:17:00 GMT" Add something like: if(is.null(data$hour),data$hour<-12 then pass data$hour as it will default to the same value as if you hadn't passed it.
