Hi, Can we attach a more descriptive "label" (I may use the wrong terminology, which would explain why I found nothing on the FAQ) to variable names, and later have an easy way to switch to these labels in plots? I fear this is not possible and one must enter this by hand as ylab and xlab when making plots. Thanks in advance, Denis Chabot

Hi, In another thread ("PBSmapping and shapefiles") I asked for an easy way to read "shapefiles" and transform them in data that PBSmapping could use. One person is exploring some ways of doing this, but it is possible I'll have to do this "manually". With package "maptools" I am able to extract the information I need from a shapefile but it is

I was just looking for an easy way to convert between COM datetime and chron datetime (both ways.) I found examples on the list, but they involved origin. Does anyone have functions for converting COM datetime <-> chron datetimethat work "safely"? David L.

Dear all, I am trying to aggregate a table (divided in two lists here), but get a memory error. Here is the code I'm running : sessionInfo() print(paste("memory.limit() ", memory.limit())) print(paste("memory.size() ", memory.size())) print(paste("memory.size(TRUE) ", memory.size(TRUE))) print(paste("size listX ", object.size(listX)))

Dear useRs, I'm struggling again with date-related stuff: I am using R to draw water levels at certain measuring stations. My data comes as a tab-delimited text file and looks like this: DATUM P1 P2 ... 2006-11-16 425.21 423.99 2006-12-15 425.12 423.97 2007-01-16 425.16 424.06 ... (measurements started in July 2004 and still continue on a monthly or bi-weekly basis) This

Hi everybody When I try example of strptime x <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960") z <- strptime(x, "%d%b%Y") The result is; > z [1] NA NA NA NA I have got the same result with complete form of month but not with numeric form. Any idea? [[alternative HTML version deleted]]

I built R 2.2.0 from source on my debian machine yesterday and updated all packages. My problem is that "dates" function from its, that my code heavely uses is now masked by "dates" from chron. How can I specify tehat I want to use dates from its or how can I prevent it from being masked? > library(its) Loading required package: Hmisc Hmisc library by Frank E Harrell Jr

Proper calendar dates in R are great for plotting and calculating. However for the non-wonks among us, they can be very frustrating. I have recently discussed the pains that people in my lab have had with dates in R. Especially the frustration of bringing date data into R from Excel, which we have to do a lot. Please find below a simple analgesic for R date importation that I discovered over

Dear R gurus, I am currently using the chron package for date manipulation in R and I am able to control the date which take the format - 1998/07/03, and - 2006-09-15 (date without time) Library(chron) As.Date(2006-09-15, format = '%Y-%m-%d') However I have a problem with the date containing only the year and month (i.e. 2006-09, 2007/08, 200609).

Hi, I don't understand the following. When I create a small artificial set of date information in class POSIXct, I can calculate the mean and the median: a = as.POSIXct(Sys.time()) a = a + 60*0:10; a [1] "2009-03-10 11:30:16 EDT" "2009-03-10 11:31:16 EDT" "2009-03-10 11:32:16 EDT" [4] "2009-03-10 11:33:16 EDT" "2009-03-10 11:34:16

Dear all I use aggregate with variables of type numeric and dates. For type numeric functions, such as sum() are very fast, but similar simple functions, such as min() are much slower for the variables of type 'dates'. The difference gets bigger the larger the 'id' var is - but see this sample code: dts <- dates(c("02/27/92", "02/27/92",

Dear Group, Having a character vector like this one: [1] "03:38:55" "07:42:38" "08:04:27" "08:17:13" "08:41:14" "08:46:58" [7] "08:47:11" "08:53:51" "08:57:51" "08:58:56" I try to do a histogram over times of a day. All I want to know, if my solution is proper or if there is another

I a have a text file where every line is like that: "2007-12-03 13:50:17 Juan Perez" ("yy-mm-dd hh:mm:ss First Name Second Name") I would like to make a data frame with two column one for date and the other one for name. When I use read.delim it was transformed in a data frame with 4 colums. Bye, Sebasti?n.

Hi all, I have problems with years of dates using "chron" package. I don't understand why R by this istruction: > dates("01/02/29",out.format="d/m/year") [1] 02/Jan/2029 > dates("01/02/30",out.format="d/m/year") [1] 02/Jan/1930 reads "29" as 2029 and "30" as 1930. How could I change to read "00" to

Dear R-helpers, I have a problem converting an object made with the 'chron' function to a POSIXct object: # Make date based on DOY dat <- chron(dates=232, origin.=c(month=1, day=1, year=2008)) dat #[1] 08/20/08 # Converting to POSIXct uses current timezone (Sydney): as.POSIXct(dat) #[1] "2008-08-20 10:00:00 EST" # Setting GMT timezone has no effect? as.POSIXct(dat,

I have a vector of over 7,000 chron dates in the format "mm/dd/yy". I need to increment each date in the vector by a standard number of months. Lapply with seq.dates is working OK; this increments the vector x by 3 months: dates(unlist(lapply(x, function(g) seq.dates(g, by="months", length=4)[4]))) But this takes about 55 seconds to run on a Windows XP 1.8 Pentium 512 RAM PC
