Dear r-users,
I have this list of student ID,
dt <- c(AA14068, AA13194, AE11054, AA12251, AA13228, AA13286, AA14090,
AA13256, AA13260, AA13291, AA14099, AA15071, AA13143, AA14012, AA14039,
AA15018, AA13234, AA13149, AA13282, AA13218)
and I would like to extract all student of ID AA14... only.
I search and tried substrt, subset and select but it fail.
substr(FKASA$STUDENT_ID, 2, nchar(string1))
Error in nchar(string1) : 'nchar()' requires a character vector
> subset(FKASA, STUDENT_ID=="AA14" )
[1] FAC_CODE FACULTY STUDENT_ID NAME PROGRAM KURSUS
CGPA ACT_SS ACT_VAL ACT_CS ACT_LED ACT_PS
ACT_IM
[14] ACT_ENT ACT_CRE ACT_UNI ACT_VOL...
Thank you so much for your help.
How do I do it?
