GrpString (version 0.3.2)

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)

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.

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.

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.
