Package MuMIn (dredge): Error in ret[, ] <- cbind(x, se, rep(if (is.null(df)) NA_real_ else df, : number of items to replace is not a multiple of replacement length.
Hello R community,
I am attempting to run multiple logistic regressions (multinomial, via
package 'nnet'), with Automated Model Selection (dredge, package 'MuMIn').
The aim is to reduce the number of predictor variables by assessing relative
performance of each variable, which can be done in a coarse fashion using
the Automated Model Selection option in package 'MuMIn'

fPortfolio constraints, maxsumW
Running R version 2.6.1 under Gentoo Linux and using the fPortfolio
package, I am having trouble specifying a sector constraint. One of the
constraints to be imposed is that assets 1 and 2 together account for no
more than 13.63% of the portfolio. My attempt at coding that
constraint, "maxsumW[1:2Assets]=13.63" fails. The relevant section of
my code file and the resulting error
