Function applied to data

Description

his is a set of function are designed to help the user to deal with the structure of new data sets.

Usage

data_str(data, min.values = 100, min.levels = 10)
y_distinct(var)
data_distinct(data)
data_cha2fac(data, show.str = FALSE)
data_few2fac(data, min.levels = 10, show.str = FALSE)
data_int2num(data, min.values = 50, show.str = FALSE)

Arguments

data	a data frame
min.values	the minimal value distinct values befor warning
min.levels	the minimal value distinct levels befor warning
var	a vector
show.str	whether to show the structure

Details

The function data_str() gives the structure of the data set.

The function data_distinct() gives the distinct values of the vectors in the data set

The function y_distinct() gives the distinct values of single vector

The function data_cha2fac() tranforms all character vectors to factors

The function data_few2fac() transform all vectors with fewer values than min.levels into factors

The function data_int2num() transform all integer vectors with more values than min.values into numeric
