GrpString (version 0.5.1)

EveString: Converts sequences of event names to strings - generalized

Description

EveString converts event names in a data frame to a string vector.

In the data frame, each row, which can have different number of event names, is converted to a string based on the conversion key. As a result, in the vector, converted strings may have different lengths.

Usage

EveString(eveName.file, eveName.vec, char.vec)

Value

The function returns a vector containing converted strings that generally have different lengths.

If not all event names are converted to characters, a warning message will be printed out.

Arguments

eveName.file

File that stores event names to be converted.

eveName.vec

Vector of event names in a conversion key.

char.vec

Characters vector in a conversion key.

Details

In general, it is not convenient to deal with data frames where different rows have different numbers of elements. Thus, it is easier to use a text file than to use a data frame when storing different numbers of event names in rows. As a result, this function utilizes a .txt or .csv file (for eveName.file) and handles such task to save users' effort.
