Thanks in advance. I have a vector of numbers which contain sections that are sequences which increase by a value of 1 followed by a gap in the data and then another sequence occurs, etc: x<-c(1:3, 6: 7, 10:13) From the vector I need to extract 2 items of information A) the first number in the sequence (e.g., 1, 6, 10) and B) how many observations were in each sequence section (e.g., 3,

Hello, and thanks in advance. I have a data.frame from which I want to count observations that occur on each day and determine the mean and std.error of said counts. For instance: x<-split(my.df, my.df$julian.days) Although I'm still in my R learning infancy I am under the impression that x is a list of data.frames subsetting my.df by group (i.e.,julian.day) where day 1:366 are

Thank you in advance for your consideration. I have a dataframe of 2000+ observations with repeated measures across approximately 300 unique individuals An event either does or does not happen (1,0) and there is a suit of independent variables associated with the event. A simplified representation follows:

I've been using strata(sampling) and found that if the dataframe to be sampled ("data") consists of repeated measures that are not sorted in order the run will fail on a given stratum. Ordering the dataframe prior to using strata() eliminates this problem. Thanks, Eric -- Eric Vander Wal Ph.D. Candidate University of Saskatchewan, Department of Biology, 112 Science Place,

Hi, I'm new to R and would like to know, how one can populate the list with array data. I'm reading a tab separated table in R. The data in the table looks something like this. #Table Data Comp    A    B    C Extracellular    103    268    535759 Nucleus    45603    47783    442744 #R code myData <- read.table("table.data",                 header=T,
