Subject: Issue with formula conversion
A random effect formulation for R package nlme is read in as a string
of characters from an input file:
ranEff <- "pdCompSymm(~1+Age)"
I need to convert 'ranEff' to a formula class. However, as shown below:
> as.formula(ranEff)
~1 + Age
the "pdCompSymm" is lost in the conversion. Any solutions? Thanks!
