print.dt.madlib: Print the result of madlib.rpart

Description

This function prints the result of madlib.rpart to the screen. It internally calls R's print.rpart function.

Usage

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

Arguments

x

The fitted tree from the result of madlib.rpart

digits

The number of digits to print for numerical values.

…

Arguments to be passed to or from other methods.

madlib.rpart is the wrapper for MADlib's tree_train function for decision trees. plot.dt.madlib, text.dt.madlib are other visualization functions.

madlib.lm, madlib.glm, madlib.rpart, madlib.summary, madlib.arima, madlib.elnet 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)

## decision tree using abalone data, using default values of minsplit,
## maxdepth etc.
key(x)<-"id"
fit <- madlib.rpart(rings < 10 ~ length + diameter + height + whole + shell,
       data=x, parms = list(split='gini'), control = list(cp=0.005))

print(fit)

db.disconnect(cid)
# }
