so have 2 strings mylist<-c('claim', 'cl.bi') , when grep('^cl\\.*', mylist) it returns both 1 , 2. if do grep('^cl\\.', mylist) it return 2. why first match 'claim' ? happened period matching? "^cl\\.*" matches "claim" because * quantifier defined thusly (here quoting ?regex): '*' preceding item matched 0 or more times. "claim" contains beginning of line, followed c , followed l , followed 0 (in case) or more dots, fulfilling requirements successful match. if want match strings beginning cl. , use one or more times quantifier, + , this: grep('^cl\\.+', mylist, value=true) # [1] "cl.bi"
