[Rd] should the text for RIGHT_ASSIGN be -> in getParseData()?

[Yihui Xie]

Hi,

The text column for '->' becomes '<-' in the data frame returned by
getParseData():

> getParseData(parse(text='1->x'))
  line1 col1 line2 col2 id parent        token terminal text
7     1    1     1    4  7      0         expr    FALSE
1     1    1     1    1  1      2    NUM_CONST     TRUE    1
2     1    1     1    1  2      7         expr    FALSE
3     1    2     1    3  3      7 RIGHT_ASSIGN     TRUE   <-
4     1    4     1    4  4      6       SYMBOL     TRUE    x
6     1    4     1    4  6      7         expr    FALSE

Is that expected?
