R by itself can give up to 9 slightly different results:
sapply(1:9, function(type) quantile(1:267, 1:3/4, type = type))
# [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9]
# 25% 67 67 67 66.75 67.25 67 67.5 67.16667 67.1875
# 50% 134 134 134 133.50 134.00 134 134.0 134.00000 134.0000
# 75% 201 201 200 200.25 200.75 201 200.5 200.83333 200.8125
