Hi Bert and All: good morning
I promise this would be the last time to write about this topic.
I come up with this R function (please see below), for sure with your help.
It works for all sample sizes. I also provided three different simple
examples.
with many thanks

##
In case anyone is still interested in my query, note that if there are
n total items to be split into g groups as evenly as possible, if we
define this as at most two different size groups whose size differs by
1, then:
if n = k*g + r, where 0 <= r < g,
then n = k*(g - r) + (k + 1)*r .
i.e. g-r g

Dear Thomas:
Thank you very much for your input in this matter.
The core part of this R code(s) (please see below) was written by *Richard
O'Keefe*. I had three examples with different sample sizes.
*First sample of size n1 = 204* divided randomly into three groups of sizes
68. *No problems
Hi Richard:
Thank you very much for your help in this matter.

Your question is ambiguous.
One reading is
n <- length(table$Data)
m <- n %/% 3
s <- sample(1:n, n)
X <- table$Data[s[1:m]]
Y <- table$Data[s[(m+1):(2*m)]]
Z <- table$Data[s[(m*2+1):(3*m)]]

Sorry, please forget about it. I believe that I am very serious when I posted
my question.

Hi Abou,
One way is to shuffle the original data frame using sample(). and
split up the result into three equal parts.
I was going to provide example code, but Avi's response popped up and
I kind of agree with him.
