Hi,
Is there any way to sort a tabel with a colum with IP-address?
table:
id rank color status ip
138 29746 yellow no 162.131.58.26
138 29746 red yes 162.131.58.16
138 29746 blue yes 162.131.58.10
138 29746 red no 162.131.58.17
138 29746 yellow no 162.131.58.14
138 29746 red no 162.131.58.13
138 29746 yellow no 162.132.58.15
139 29746 green no 162.252.20.69
140 29746 red yes 162.254.20.71
141 29746 yellow no 163.253.7.153
142 31804 green yes 163.253.20.114
144 32360 black yes 161.138.45.226
....
Unfortunately, order doesn't work as I want.
I found an half solusion from John:
mysort <- function(x){
sort.helper <- function(x){
prefix <- strsplit(x, "[0-9]")
prefix <- sapply(prefix, "[", 1)
prefix[is.na(prefix)] <- ""
suffix <- strsplit(x, "[^0-9]")
suffix <- as.numeric(sapply(suffix, "[", 2))
suffix[is.na(suffix)] <- -Inf
remainder <- sub("[^0-9]+", "", x)
remainder <- sub("[0-9]+", "", remainder)
if (all (remainder == "")) list(prefix, suffix)
else c(list(prefix, suffix), Recall(remainder))
}
ord <- do.call("order", sort.helper(x))
x[ord]
}
mysort (data$ip) captured only the ip-adresse. How can I capture the whole
table and sorted?(ID rank color status ip)
Thank you in advance.
