I am trying to create a new column that will return Yes or No based on conditions of another column.
I have tried to use grepl
, substr
and nchar
, ifelse
. The issue is that the data has characters and numbers in the column that I am trying to condition.
(nchar(as.character(expo$BuyerNumber)) == 3)
(substr(as.character(expo$BuyerNumber),1,1 == 6))
I want to create aa new column that will have yes or no if the following conditions are met. If the first number starts with 6 and is of length 3 then yes if not then no will be returned.
Examples:
610
610B
620C
All above would return yes
426
62B
21C
All above would return no
One problem, I see, might be that you are comparing substr (which will give a character) to a number. That is likely to give false boolean. Something like below.
(nchar(as.character(expo$BuyerNumber)) == 3)
(as.integer(substr(as.character(expo$BuyerNumber),1,1)) == 6)
If it does not work, please let me know.
