how to use AND in grepl
.......
$TR :int 100,210,548,546,.....
$Command :factor W/2229 levels "_localize_PD","_localize_tre_t2","_abdomen_t1_seq","knee_pd_t1_localize","pd_local_abdomen_t2"...
I have tried this but I did not get result:
t2pd=subset(df,grepl("t2",Command) & grepl("pd",Command))
does anyone know how to apply AND in grepl?
Thanks
