This OUT_DATED function produces a data.frame describing one or many metric variables selected from a data.frame DFR by their names in a character vector COLUMNS SPLIT is a group variable which may be left out

DescribeMetricBySplit(DFR, COLUMNS = NULL, SPLIT = NULL, LONGNAMES = NULL,
  SEL = "All", DIGITS = 3, ALL = T, FORTRANSPOSITION = F)

Arguments

DFR

is a dataframe (if vector, COLUMNS must remain NULL)

COLUMNS

=NULL colnames in DFR to be described (at least one, unless DFR is a vector)

SPLIT

=NULL split factor (variable), if NULL simple description, NULL is default

LONGNAMES

=NULL optional long names for variables specified by COLUMNS

SEL

="ALL" if specified select statistics from c("MEAN", "SD", "P25", "MEDIAN", "P75", "MIN", "MAX", "MAD", "NVALID", "NMISSING")

DIGITS

Number of digits for percentages , digits=1 is default

ALL

=T If TRUE, also overall statistics are calculated

FORTRANSPOSITION

=F Set to T if you later want to transpose the resulting data.frame - VARIABLE stays redundant

Value

a data.frame with statistics for each COLUMN by the group variable SPLIT
