Symbolic Regression Trees
sym.rt(
formula,
sym.data,
method = c("cm", "crm"),
minsplit = 20,
maxdepth = 10
)
formula |
a formula, with a response but no interaction terms. If this a a data frame, that is taken as the model frame (see model.frame). |
sym.data |
a symbolic data table |
method |
cm crm |
minsplit |
the minimum number of observations that must exist in a node in order for a split to be attempted. |
maxdepth |
Set the maximum depth of any node of the final tree, with the root node counted as depth 0. Values greater than 30 rpart will give nonsense results on 32-bit machines. |
