Hello!
I am producing a set of images and I would like them to be sorted by names I give. I was able to produce my names and add integer to them. That is easy. But my problem lies in sort of file from this process:
figure_10.png figure_11.png figure_12.png ... figure_1.png figure_20.png ...
So I would like to convert integers to something like 01 if upper limit for
this conert is 10 or 001 for 100. I wrote a simple function (see below), but I do not know how this limit stuff can be imporved to work really well with default. Any suggestions?
int2char <- function(x, limit = max(x)) { # Description:
# Converts integer to character such that numbers bellow limit get 0 in
# front
# Gregor GORJANC, 2005-01-05 # Arguments:
# x: vector of numbers
# limit: limit up to which numbers should get 0 in front, default
# max(x) # Examples:
# a <- seq(0, 20, 1)
# int2char(a) # this does not work OK
# int2char(a, limit = 10) # this does work OK # How to:
# I would like that default would be more efficient - so it would
# recognize that let say limit 20 in example above should actually be
# 10 and so on. # Code:
for (i in 1:length(x)) {
if (x[i] < limit) {
n[i] <- paste("0", x[i], sep = "")
} else {
n[i] <- as.character(x[i])
}
}
return(n)
}
