Dear user,
I have a monthly time series data (length 144), as ts (time series)
object in R. I would like to
1-extract vector of let say January data (a vector of length 12),
2-extract the monthly means, sums (a vector of length 12).
Many tahnks in advance
Yours,
Hamid
Dear All,
I have a data frame (mydata), with let say 5 columns V1,V2,...,V5.
(we know the power set of {V1,V2,..,V5} has 2^5-1 elements). I need
to construct a vector T of length 5 which its i-th element is the
maximum of (let say) mean values obtained based on the columns subset
of size i. (MY F

Dear All,
I am trying to build a program which will take repeated samples without
replacement from a population of values. The interesting catch is that I
would like the sample values to be removed from the population, after each
sample is taken.
For example:
pop<-c(1,5,14,7,9,12,18,19,65,54)
