[R] RCurl : All connection are used ?
     Hi everybody,
I got a problem with the ftpUpload function from the RCurl package. My goal is
to Upload a lot of files from a local directory to a web server.
1st try :
for (i in 1:length(file)){
     ftpUpload(what=files[i],to=files[i])
}
At i=11 I get : (my server has only 10 available open connections available) :
Erreur dans curlPerform(url = to, upload = TRUE, readfunction =
uploadFunctionHandler(what, :
 Got a 421 ftp-server response when 220 was expected
2 nd Try :
ftpConnection=getCurlHandle(userpwd=ftp$userpwd,maxconnects=1,fresh.connect=0)
for (i in 1:length(file)){
     ftpUpload(what=files[i],to=files[i],curl=ftpConnection)
}
And I got this error after 30 files (the error is not linked to the web server
but to the R session) :
Error in file(file, rb) : all conection are used
I read the documentation and the options from curl library but I can't find how
to solve my problem even if I think that the problem is linked to not closing
the position I opened. Do you have any idea how to solve it ?
Thanks,
Olivier Merle

[R] Different time between date() and Sys.date()
Hi, I got two different times between these functions : date() [1] Thu Oct 21 12:11:37 2010 Sys.time() [1] 2010-10-21 10:11:40 GMT I know that its because I did Sys.setenv(TZ=GMT). Even if my system is set by default at CEST. I think that the difference between date() and Sys.time() is equal to the difference between CEST and GMT. I would like to get the time of my machine even if I set GMT as a time zone with the Sys.time() function. How can I get the real time from the Sys.time() function ? Or I can really set my time zone to GMT to get the real time with Sys.time() ? Thanks, Olivier Merle Une messagerie gratuite, garantie à vie et des services en plus, ça vous tente ?

Re: [R] Different time between date() and Sys.date()
Thanks for you answer. It s sufficient but I d like to know why my system think I am CEST and yours think your are EDT. Can I change it ? Do you know where can I find a list of the timezone ?

[R] Data.frames : difference between x$a and x[, a] ? - How set new values on x$a with a as variable ?
Hi, I got two questions : 1st Question          a=S          b=data.frame(S=3)          do.call(`-`,list(do.call(`$`,list(b,S)),5)) = How can I put new values on S column having the column name as a variable ? 2 nd Question       a=S      b=data.frame(S=3)      b[,S]=list(1:10) #Doesnt works      b$S=list(1:10) #Works = Isnt the same thing ? What is the difference between these two things ? Thanks, Une messagerie gratuite, garantie à vie et des services en plus, ça vous tente ?

Why are you setting a equal to S but then never using it? = How can I put new values on S column having the column name as a variable ? I'm having trouble parsing this. What exactly do you want to do? 1 - Put a list as an element of a data.frame. That's quite convenient for my pricing function.  2 nd Question       a=S      b=data.frame(S=3)      b[,S]=list(1:10) #Doesnt works      b$S=list(1:10) #Works = Isnt the same thing ? What is the difference between these two things ? I believe b[[S]] is the same as b$S, b[,S] is different. But I have to question your assertion that b$S=list(1:10) Works. This is a very odd construction (putting a list as an element of a data.frame) and is almost certainly not what you want. 2 - That's what I want. I figured out just five minutes ago that b[[S]] works because it's the same thing as b$S. But I still dont know what is b[,S] compared to b[[S]] Thanks, Une messagerie gratuite, garantie à vie et des services en plus, ça vous tente ?

[R] Using library and lib.loc
Hi, I didn't find any post on this subject so I ll ask you some advices. Let's say that I have two library trees. Number 1 is the default R library tree on path1 Number 2 is another library tree on a server with all packages on path2. When I set library(aaMI,lib.loc=paths2) it loads the package even if its not on default R library When I set library(fOptions,lib.loc=paths2) it doesn't load because timeSeries is not on default R library (timeSeries is a required package for fOptions) library(fOptions,lib.loc=.lib.loc) Le chargement a nécessité le package : timeDate Le chargement a nécessité le package : timeSeries Erreur : le package 'timeSeries' ne peut être chargé De plus : Message d'avis : In library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc) :  aucun package nommé 'timeSeries' n'est trouvé (Sorry for french error message. By the way, how can I set error in French (setting language in English in R installation is not sufficient !) How can I set lib.loc for every package that I will load ? Or is there any global way of doing this ? Thanks, Olivier Une messagerie gratuite, garantie à vie et des services en plus, ça vous tente ?
