hi,
I want to know just enter a string value
entering a numeric value is make with the function scan () or scan (nmax ..)
but it does not work for string
my goal is to enter three string: name and surname and date of birth
I try with this code but it shows me errors
print ("enter the name")
name <- scan (nmax = 1)
print ("enter the first name")
firstName <- scan (nmax = 1)
print ("enter the date of birth")
BirthDate <- scan (nmax = 1)
best regards
alen

Alen, look at ?scan and there particularly at the argument 'what'.
