## S3 method for class 'imptree'
print(x, digits = getOption("digits"), sep = "\t",
  ...)

`x`	Object of class `imptree`. See details.
`digits`	a non-null value for digits specifies the minimum number of significant digits to be printed in values. The default uses `getOption("digits")`. Non-integer values will be rounded down, and only values greater than or equal to 1 and no greater than 17 are accepted.
`sep`	Separator between the displayed IPDistribution objects. (Default: `'\t'`)
`...`	Additional arguments; ignored at the moment

An existence check on the stored C++ object reference is carried out at first. If the reference is not valid the original call for "object" is printed as error.

For a more detailed summary of the tree summary.imptree.

Returns the calling object invisible.
