I would like to access to the min and max of a specific column from my dataframe but I don't have the header of the column, just its number, so I should I do using scala?
maybe something like this :
val q = nextInt(ncol) //we pick a random value for a column number
col = df(q)
val minimum = col.min()
Sorry if this sounds like a silly question but I couldn't find any info on SO about this question
