Data output: Write single-case data to a .csv-file

Description

This function restructures and writes single-case data into a .csv-file.

Usage

write_scdf(data, filename = NULL, sep = ",", dec = ".", ...)

Arguments

data	A single-case data frame. See scdf() to learn about this format.
filename	A character string defining the output file name (e.g. "scdf_data.csv". If NULL (default), the data are written to the console.
sep	The field separator string. Values within each row of x are separated by this string.
dec	The string to use for decimal points in numeric or complex columns: must be a single character.
...	Further arguments passed to write.table.

Details

This is a wrapper for the write.table function with predefined parameters. It converts the single-case data file into a data frame and writes it to a .csv-file. Each single-case data set is stacked below each other and an additional column "case" is added to identify the different single-cases.

Value

Invisibly returns NULL.

Examples

## write single-case data to a .csv-file
filename <- tempfile(fileext = ".csv")
write_scdf(exampleAB, filename)

## write multiple cases to a .csv-file with semicolon as field and comma as
## decimal separator
write_scdf(Grosche2011, filename, sep = ";", dec = ",")

## read_scdf and write_scdf
write_scdf(exampleA1B1A2B2_zvt, filename)
dat <- read_scdf(filename, cvar = "case", pvar = "part",
                 dvar = "zvt", mvar = "day")
res1 <- describe(exampleA1B1A2B2_zvt)$descriptives
res2 <- describe(dat)$descriptives
all.equal(res1,res2)
