When using the method blackboost_fit of the package mboost appear following
error :
Error in party:::get_variables(o...@responses) :
trying to get slot "responses" from an object (class "boost_data") that is not
an S4 object
Simple test case that produce bug:
dt=expand.grid(y=c(2,3,4), x1=c(1,2), x2=c(1,2))
library(mboost)
bd=boost_dpp(y ~ .,data=dt, weights = NULL)
blackboost_fit(bd,
tree_controls = ctree_control(
teststat = "max",
testtype = "Teststatistic",
mincriterion = 0,
maxdepth = 2
),
fitmem = ctree_memory(
bd,
TRUE
),
family = GaussReg(),
control = boost_control(
mstop = 2
),
weights = NULL
)
Test case session on my computer:
