describe {prettyR} | R Documentation |
Describes a vector or the columns in a matrix or data frame.
describe(x,num.desc=c("mean","median","var","sd","valid.n"),xname=NA)
x |
A vector, matrix or data frame. |
num.desc |
The names of the functions to apply to numeric data. |
xname |
A name for the object x , mostly where this would be a very long string
describing its structure (e.g. if it was extracted by name from a data frame). |
describe
displays a table of descriptive statistics for numeric and
factor variables in the object x
. The summary measures for numeric
variables can easily be altered with the argument num.desc
. Pass a
character vector with the names of the desired summary measures and these
will be displayed at the top of the numeric block with their results beneath
them. If quantiles are desired, the user will have to write wrapper functions
that call quantile
with the appropriate type or probabilities and use
the names of the wrapper functions in num.desc
.
