Hello,
Package stringr has functions str_sort and str_order, both with an
argument 'numeric' that will sort the numbers correctly.
Maybe that's what you are looking for, see the example below.
x <- sample(sprintf("ab%d", 1:20)) # shuffle the vector
stringr::str_sort(x, numeric = TRUE) # sort considering the numbers
Hope this helps,
Rui Barradas

Hi,
Running a simple syntax set to review entries in dataframe columns. Here
is the working code.
Data <- read.csv("./input/Source.csv", header=T)
describe(Data)
summary(Data)
unique(Data[1])
unique(Data[2])
unique(Data[3])
unique(Data[4])
I would like to add sort the unique entries. The data in the various
columns are not defined as numbers, but also text. I realize 1 and 10
will not sort properly, as the column is not defined as a number, but
want to see what I have in the columns viewed as sorted.
QUESTION
What is the best process to sort unique output, please?
Thanks.
