Dear all, I am encountering a problem with lattice in the current version 0.14-13 with R version 2.4.0 on a Windows XP system. For example, histogram(~voice.part, singer) is not labeling the x labels according to the factor levels of voice.part, which it should do (and has done in former versions of lattice, as far as I remember). In addition, I get the warnings Warning messages: 1:

Dear all, on my Windows XP R 2.4.0 version with Package its version 1.1.4 I have a problem with str() applied on an its-object after a simple matrix manipulation on the its object (see below). I am not sure, whether this a problem with my application, its or str(). Of course, one can make > str(core(its(mat)) / 1) num [1:2, 1:3] 1 2 3 4 5 6 - attr(*, "dimnames")=List of 2 ..$

Dear all, I have problems to compile a DLL for Windows XP with R version 2.5.1 (2007-06-27).

Dear all, I would like to inquire, if it is a desired feature that the combination with rbind() of two data frames with factors columns does not sort the factors levels of the combined data frame. > str(rbind(data.frame(a = factor(c(4, 3))), data.frame(a = factor(c(2, 1))))) 'data.frame': 4 obs. of 1 variable: $ a: Factor w/ 4 levels

R users: I'd like to get some insight on an error I encounter when attempting to work with two moderately sized sets of time series data. FYI - I'm using the following versions of R and supporting packages on a Windows 2000 OS: - R version 2.4.1 (2006-12-18) - zoo version 1.2-2 - chron version 2.3-10 The two time series I'm working with are from the summer of 2004 and are: 1.)

Hi all, I am *completely* lost in trying to solve a relatively simple task. I want to compute the relative number of occurences of an event, the data of which sits in a large table (read from file). I have the occurences of the events in a table 'tt' 0 2 10 11 13 14 15 15 6 1 3 8 15 10 .. meaning that event of type '0' occurs 15 times, type '2' occurs 6 times

Dear all, according to the Help-page of DateTimeClasses {base} I should be able to do time - z with time date-time objects z a numeric vector (in seconds) or an object of class "difftime". However, on R version 2.6.0 (Windows XP) I get > Sys.time() - as.difftime(c("0:3:20", "11:23:15")) Time differences in mins [1] 1191837998 1191837318

The following creates a time series tt1 whose values rise from 1 to 20 and another time series tt2 each of whose values are 10 larger than the corresponding value in tt1. When we attempt to bind them together as columns, the entry after Dec 1960 is erroneously listed as NA 1960 instead of Jan 1961. If n is changed to either 19 or is changed to 21 in the example below, the example suddenly

Dear All I am trying to graph a proportion and CI95% by a factor with ooplot (any other better solution ?) It works well until I try to add the confidence interval. this is the error message and and a description of the data: > dat1 PointEst TT1 1 3.6 TT2 2 5.0 TT3 3 5.8 TT4 4 11.5 TT5 5 7.5 TT5 6 8.7 TT7 7 17.4 > dat2

Hi, I was trying to get hyperlinks using xtable, but couldn't get the hyperlinks to function properly. For example, if I use ## Try to link NY times website to every figure in column 4 mat <- matrix(1:43,6,5) mat[,5] <- "http://nytimes.com" for(i in 1:nrow(mat)){ strr <- paste('<a href="', mat[i,5],'">', mat[i,4], '</a>',

Hello, I wrote a function in R which uses tcltk package .... essentially I wanted to give within that function, a widget with 2 radiobuttons to choose between plotting Precip and Temperature plots. After the user has chosen one of the radiobuttons there is another widget that asking him to identify outliers. However, I am having a lot of problems...what R does is evaluate the whole function

Folks, I'm checking the structure of a dataframe for duplicate parameters at a site station (i.e depth should be measured once, not twice), using aggregate to count each parameter within a site station. The fake data below has only 26000 rows, and takes roughly 14 seconds. My real data has 750000 rows and I had to stop execution after about an hour. The by() function is faster, but I

I have a data frame where I need to subset certain rows before I compute the mean of another variable. However, the value that I need to subset by is found in multiple columns. For example, in the data below the value R0000160 is found in the first and second columns (itd_1 and itd_45). These data are student responses to multiple choice test items from a computer adaptive test. So, the variable

Sorry, for my mail from last night contains no subject. Therefore, I send it again and two tcltk questions are appended. ---------------------------------------------------------------------------- Prasad wrote: > I wrote a function in R which uses tcltk package .... essentially I wanted > to give within that function, a widget with 2 radiobuttons to choose > between plotting Precip

Using Tinn-R (in windows) is possible to run latex and R from the same editor, which was great. Now, I am using Ubuntu-linux, which has been better than WinXP. Currently, I am using Emacs (and then install ESS) for running LaTeX and R from a same editor-program (like i was doing with Tinn-R in windows). Nevertheless, and even though i have been using Emacs for almost 2 years, it is not as

Hi everybody How do I do to calculate the median and average of a colum of time data like this: "8:50:10". I also need to plot the time difference between two colums Thanks a lot -- View this message in context: http://n4.nabble.com/median-for-time-data-tp932287p932287.html Sent from the R help mailing list archive at Nabble.com.

How can I extract only the time component from an POSIXlt object? For example if I try the following it still returns both the date and time... >as.POSIXlt(tr.date[1]) [1] "2010-10-18 21:46:53" >as.POSIXlt(tr.date[1],"%H:%M:%S") [1] "2010-10-18 21:46:53" round and trunc don't help... is there an "as.Time" equivalent to as.Date ? Thanks,
