convert integers, string to integer vector
Functions for conversion to string representation of integers to arbitrary bases
NdM( x, B=10 )
int2ASCII( n)
int2B( n, B=10, space, plus=lead, lead="",just=c("left","right","center","none") )
int2Oct( n )
int2Hex( n )
strRound( str, digits = getOption("digits"), B=10)str |
String representing a real |
n |
Integer vector |
B |
1 < integer < 17, base of representation |
space |
Integer, space for conversion |
plus |
string for signifying positive values, usually "" or "+" |
lead |
string for insertion between sign and first significant digit, usually "" or "0" |
just |
String for choosing kind of justification within 'space', partial matching allowed |
x |
Vector of reals |
digits |
no. of digits for roeunding |
