Details

The function assumes the names are comma separated with lastname, firstname order. The code separates the names, removes blanks from the first name, and finds a unique set of names. If first names are not unique, the function extracts the first letters of the last names and the duplicated names and appends with a period.

Examples

g.first =c("Jason","Skyler","Adrian","Berkley","Jack",'David',
'David', 'Jim', 'Jim')
g.last =c('Joyce', 'Einstein', 'Hertz', 'Bailey', 'Compton',
'Jones', 'Wilson', 'Smith', 'Anderson' )

c2 = paste(g.last, g.first, sep=', ')

K = GetStudentNames(c2)
