Digits after decimal point in pandoc.table

[pflick]

It seems that the digits option in pandoc.table results in the total number of digits, not digits after the decimal. Here is an example:

a<-c(10.12304,9.321,0.12345,82.77123)
b<-c(12.0009,1.0987,0.9876,4.3321)
tbl<-rbind(a,b)

pandoc.table(tbl, digits=4)

results in

------- ------- ------- -------- -------
 **a**   10.12   9.321   0.1235   82.77 

 **b**    12     1.099   0.9876   4.332 
------- ------- ------- -------- -------

There doesn't seem to be a way to get x digits after the decimal point if your numbers vary in length. Is this a feature that could be added?
Thank you for pander!

Yeah, so digits stands for the number of signigicant digits as in format. I think you are looking for a mix of digits and round, eg:

> pandoc.table(tbl, digits=4, round = 4, keep.trailing.zeros = TRUE)

------- ------- ------- -------- --------
 **a**   10.12   9.321   0.1234   82.771 

 **b**   12.00   1.099   0.9876   4.332  
------- ------- ------- -------- --------

Or even more:

> pandoc.table(tbl, digits=5, round = 4, keep.trailing.zeros = TRUE, justify = 'right')

------- -------- -------- -------- ---------
  **a**   10.123   9.3210   0.1234   82.7712

  **b**   12.001   1.0987   0.9876    4.3321
------- -------- -------- -------- ---------

I hope this helps and closing the ticket for now -- as having no better idea around this, but feel free to come back with suggestions and reopen.
