Description Usage Arguments Value Note Author(s) Examples

Description

Given the filename of a file compiled from the vest, this function imports the speficied file into the R environment as a dataframe.

Usage

1
import_vest(filename,prefix,suffix)

Arguments

filename

The complete filename (including path, name and extension) to the file you want to import into R.

prefix

(Optional, no default) Sometimes it is handy to import the column names with a prefix (e.g. "VEST_") so they are unique within the dataframe if you want to use the time series to compare with another instrument. The result of specifying a prefix is that all columns in the imported dataset (except for PosixTime) are named (e.g. "VEST_") VEST_dect, VEST_2100UL, etc.

suffix

(Optional, no default) Similar to above. The result of specifying a suffix (e.g. "_Vm") is that all columns related to frequency bands show this suffix in their variable name (e.g.) DECT_Vm, 2100UL_Vm etc.

Value

The result is an R dataframe of your vest file which is ready to work with.

Note

A small vest example .csv file -at least the way it looks for now- is available as an example, but the format will likely change. To be continued...
