R/S compatibility in passing a formula
Sat, 10 Apr 1999 17:05:35 -0500 (CDT)
In S3 if you are passing an evaluated formula to another function that
will store it and use it in printing (such as a model-fitting function), you
usually want to unclass the formula. Otherwise, the formula that gets
stored looks very ugly when printed. A trick to do the unclassing is to pass
form = c( myFormula )
In R this has the effect of making form a list rather than a call. It
seems that passing
form = as.vector( myFormula )
will work in both dialects. Anyone else have experience with this?
