how to us DataFrame.na.fill based on condition

[Vishnu Viswanath]

Hi

Can someone tell me if there is a way I can use the fill method
in DataFrameNaFunctions based on some condition.

e.g., df.na.fill("value1","column1","condition1")
        df.na.fill("value2","column1","condition2")

i want to fill nulls in column1 with values - either value 1 or value 2,
based on some condition.

Thanks,
