I have created a list of matrices using sapply or lapply and wish to extract
each of the matrices as a matrix. Some of them are 2x2, 3x3, etc.
I can do this one at a time as:
M1-as.matrix(D[[1]])
How can repeat this process for an unknown number of entries in the list? In
other words, how
In my code, I would like to replace entries in t with
entries from a random normal distribution.
n-10
nl-round(1.5+rexp(1,rate=2)
rate=2))
nl
[1] 2
r-1:n
s-sort(sample(r,nl))
t-match(r,s)
r
[1] 1 2 3 4 5 6 7 8 9 10
s
[1] 3 8
t
[1] NA NA 1 NA NA NA NA 2 NA NA
