Hi everyone, I'm using the poLCA module for some analysis work. Basically, Im using the command >poLCA(f, data=response,nclass=2) This returns a poLCA object (a list)
From this data, I need to retrieve certain indexes, such as[[5]] as seen
below.
[[5]]
Pr(1) Pr(2) Pr(3)
class 1: 0 1.0 0.0
class 2: 0 0.5 0.5
1) The structure shown in [[5]] above is a matrix, isn't it ?
2) how can I specifically retrieve this matrix (retrieve by ID, I guess) ?
Hi. If the list is in the variable "poLCA", then try a <- poLCA[[5]] a Whether this is a matrix may be checked using class(a) Hope this helps. Petr Savicky.
