print.rf.madlib: Print the result of madlib.randomForest

Description

This function prints the result of madlib.randomForest to the screen. It internally calls R's print function for random forests.

Usage

# S3 method for rf.madlib
print(x, digits = max(3L, getOption("digits") - 3L),
        ...)

Arguments

x

The fitted forest from the result of madlib.randomForest

digits

The number of digits to print for numerical values.

…

Arguments to be passed to or from other methods.

madlib.randomForest is the wrapper for MADlib's forest_train function for random forests.

madlib.lm, madlib.glm, madlib.rpart, madlib.summary, madlib.arima, madlib.elnet, madlib.rpart are all MADlib wrapper functions.

Examples

# NOT RUN {
<!-- %% @test .port Database port number -->
<!-- %% @test .dbname Database name -->
## set up the database connection
## Assume that .port is port number and .dbname is the database name
cid <- db.connect(port = .port, dbname = .dbname, verbose = FALSE)

x <- as.db.data.frame(abalone, conn.id = cid, verbose = FALSE)
lk(x, 10)

## random forest using abalone data, using default values of minsplit,
## maxdepth etc.
key(x)<-"id"
fit <- madlib.randomForest(rings < 10 ~ length + diameter + height + whole + shell,
       data=x)

print(fit)

db.disconnect(cid)
# }
