seq - How to generate a sequence in R, that starts with 01 and ends with 99? -


i want: 01 02 03 ... 10, 11, 12 ... 97, 98, 99

i have tried using following:

seq("01":"19") # doesn't paste0("0",seq("01":"19")) # doesn't 

please suggest something!

we can use sprintf

sprintf("%02d", 1:99) #[1] "01" "02" "03" "04" "05" "06" "07" "08" "09" "10" "11" "12" "13" "14" "15" "16" "17" "18" "19" "20" "21" "22" "23" "24" "25" "26" "27" "28" "29" "30" "31" "32" #[33] "33" "34" "35" "36" "37" "38" "39" "40" "41" "42" "43" "44" "45" "46" "47" "48" "49" "50" "51" "52" "53" "54" "55" "56" "57" "58" "59" "60" "61" "62" "63" "64" #[65] "65" "66" "67" "68" "69" "70" "71" "72" "73" "74" "75" "76" "77" "78" "79" "80" "81" "82" "83" "84" "85" "86" "87" "88" "89" "90" "91" "92" "93" "94" "95" "96" #[97] "97" "98" "99" 

or package option str_pad

library(stringr) str_pad(1:99, pad = 0,width = 2 , "left")
