# Example 1
Vector <- "sum(F17:G18)+G190*G2+ sum(A1:B2)"
patt <- '[A-F]+[0-9]+'
Matches (Vector,patt)
# [A-F]+[0-9]+
# sum(F17:G18)+G190*G2+ sum(A1:B2) Character,3
# Example 2
Matches (c(Vector, "sum(A1:B2)"),patt)
# [A-F]+[0-9]+
# sum(F17:G18)+G190*G2+ sum(A1:B2) Character,3
# sum(A1:B2) Character,2
# Example 3
Matches (Vector =c("Patrick Pasot, Patrick Schmidt","Patrick Denker"),
patt =c("Patrick","Schmidt")
) # Matches
# Patrick Schmidt
#Patrick Pasot, Patrick Schmidt Character,2 "Schmidt"
#Patrick Denker "Patrick" Character,0
# Example 4
