Rounding off values in a column - SparkR

Question

I have the below values in one of the column in a dataframe

231204.66666666666 376.0 346593.5 802.0 346594.5 801.0 346595.5 800.0 null 0.0

I just want the absolute value in this column. How can I do that in SparkR?

I found abs and round from SparkR which can do this job. But unfortunately it is not exported. Getting the below exception when I use Spark::abs(df$col)```

Error: 'abs' is not an exported object from 'namespace:SparkR'

I am getting the same error for SparkR::round as well.

I tried the below, but the column value not changed.

df$col <- abs(df$col)

How can I get the absolute value in the column?

the sample you gave does not change under abs(). try round(abs(df$col),0) — Zahiro Mor

The sample you gave does not change under abs(). abs has to be combined with round. Like, round(abs(df$col))
