Full_Name: S?bastien Villemot Version: 2.4.0 OS: Debian testing Submission from: (NULL) (62.212.121.128) Hi, In the mle() function of the stats4 package, there is a bug in the ordering of the variables given in the 'start' argument. By just changing the order of the variables listed in the 'start' list (the initialization values), it is possible to obtain different estimation

Hello Everyone, I am using R 2.15.0 and I came across this behaviour and I was wondering why I don't get an integer vector or and integer matrix with the following code: > z <- c(1, 2:0, 3, 4:8) > typeof(z) [1] "double" > z <- rbind(1, 2:0, 3, 4:8) Warning message: In rbind(1, 2:0, 3, 4:8) : number of columns of result is not a multiple of vector length (arg

Hi all I love Sweave; use it all the time. But I recently received a new computer, and ever since I have had a problem I've never seen before.

Something probably obivous but I don't see it. I needed to find the first 1 or two digits of some 5 and 6 digit numbers since they identified research sites while the rest of the number was the plot id. I converted the numbers to characters, got the first 1 or 2 characters as appropriate and went to add the new vector to the data.frame. For some reason R is insisting on turning the

Preparing a paper for a medical journal. Using the prop.test() function in R (v2.4.0) to compare two groups' response to data like the following. A sample of 100 individuals from Population I, 18 with positive readings from a certain test, vs. A sample of 148 individuals from Population II, 61 with positive readings. Results look like this: R version 2.4.0 Patched (2006-11-25

Hello R people, How can I compute the mean of the "Pulse_rate" column of the data frame or matrix from the following character object called "str_got". It has 14 entries and each entry has 8 values, separated by commas. Please go thru the following R commands to know how I tried to unstring and unlist the values to form a data frame. > str_got [1]

Does anyone know why a data frame created with empty character columns converts them to integer columns? > df<-data.frame(a=character(0),b=character(0)) > df<-rbind(df,c("a","a")) > typeof(df[1,1]) [1] "integer" AsIs doesn't help: > df<-data.frame(a=I(character(0)),b=I(character(0))) > df<-rbind(df,I(c("a","a")))

Hi Ben Thanks for your answer I have already tried this, as well as x <- as.POSIXct(strptime("2002-02-02 02:02", "%Y-%m-%d %H:%M")) It works! But it does not fix it widely for all tests used during the "make check" step at compile time. Unless I patch all of them. There is something with localtime but I cannot find what.

Hi, I still have little ability to predict how these functions will treat the columns of data frames: > # Here's a data frame with a column "a" of integers, > # and a column "b" of characters: > df <- data.frame( + a = 1:2, + b = c("a","b") + ) > df a b 1 1 a 2 2 b > > # Except -- both columns are characters: >

I found this part in the documentation of 'factor'. 'factor(x, exclude=NULL)' applied to a factor is a no-operation unless there are unused levels: in that case, a factor with the reduced level set is returned. If 'exclude' is used it should also be a factor with the same level set as 'x' or a set of codes for the levels to be excluded.
