Hi All,

Is there any function in R which does what Floor or Ceiling in Excel.

Excel can take 2 arguments to FLOOR function while R doesn't.

I need the following which is done in excel

Base = 0.5
Floor(126.6,Base) = 126.5
Ceiling(126.6, Base) = 127

Base = 1
Floor(126.6, Base) = 126
Ceiling(126.6, Base) = 127

I tried round, floor, ceiling, trunc in R but none does this job. 

Pls Help/Thanks
