I can see the source code of let in kotlin-stdlib-common-1.2.51.jar where path is kotlin -> Standard.kt (or file name showing as StandardKt.kotlin_metadata). I am doing same command.


let


kotlin-stdlib-common-1.2.51.jar


kotlin -> Standard.kt (or file name showing as StandardKt.kotlin_metadata)



Below is code of that fun


fun


/**
* Calls the specified function [block] with `this` value as its argument and returns its result.
*/
@kotlin.internal.InlineOnly
public inline fun <T, R> T.let(block: (T) -> R): R
contract
callsInPlace(block, InvocationKind.EXACTLY_ONCE)

return block(this)



Versions I am using are


Android Studio 3.1.3
Build #AI-173.4819257, built on June 4, 2018

What I need to do is grouping on the first field and counting the occurrences of 1s and 0s. I was hoping to do something like num_fav = count((col("is_fav") == 1)).alias("num_fav") num_nonfav = count((col("is_fav") == 0)).alias("num_nonfav") df.groupBy("f").agg(num_fav, num_nonfav) It does not work properly, I get in both cases the same result which amounts to the count for the items in the group, so the filter (whether it is a 1 or a 0) seems to be ignored. Does this depend on how count works? count 1 Answer 1 There is no filter here.
