within group sequential subtraction
...uld like to do sequential subtractions within a group so that I know the
time between separate observations for a group of individuals.
My data:
data <- structure(list(group = c("IND1", "IND1", "IND2",
"IND2", "IND2", "IND3", "IND4", "IND5",
"IND6", "IND6"), date_obs = structure(c(6468,
7063, 9981, 14186, 14372, 5129, 9767, 11168, 10243, 10647), class =
"Date")), .Names = c("group",

Subsetting a data frame
...h subsetting data frames:
I have a large database of medical records and I want to be able to match

choosing selective data with permutations
Hello,
I am a R beginner and hoping to obtain some hints or suggestions about
using permutations to sort a data set I have.
Here is an example dataset:
Ind1 11 00 12 15 28
Ind2 21 33 22 67 52
Ind3 22 45 21 22 56
Ind4 11 25 74 77 42
Ind5 41 32 67 45 22
This will be read into a variable using read.table. What I want to do
is permute these individuals and every time pick 3 individuals and
write them to a new variable. I want to do this 100 times so that in
the end I will have 100 tables containing...
