options(OutDec= ",") and aes_string()

[schloerke]

aes_string is having trouble with decimal values. Should I be calling the value inside a quote (as a character) to make it work properly? Seems odd.

# works ok
aes_string(x = 2.5)
aes(x = 2.5)

options(OutDec= ",")

aes(alpha = 0.4)
# List of 1
#  $ alpha: num 0,4
aes_string(alpha = 0.4)
# Error in parse(text = x) : <text>:1:2: unexpected ','
#1: 0,
#      ^
aes_string(alpha = "0.4")
# List of 1
#  $ alpha: num 0,4


# wrong
aes_string(alpha = 0,4)
# List of 2
#  $ x    : num 4
#  $ alpha: num 0

Thank you,
Barret
