Convert code from DataFrames version to DataFramesMeta

DataFrames (successful):

lst = describe(df)[(describe(df)."nmissing" .> 0 .&& describe(df)."variable" .!= :x26), :variable]

DataFramesMeta:

lst = @chain describe(df) begin 
	@rsubset :nmissing > 0
	@select :variable
        @rsubset :variable != Symbol("x26")
end |> x -> vec(x[!, 1])

Error:

MethodError: no method matching isless(::Int64, ::Symbol)

Firstly, I filtered all the row in df with :nmissing > 0 then select only the :variable column, finally turn that column to a vector. That’s my task. How can I fix the error?

After some testings, I can fix my code with parenthesis

lst = (@chain describe(df) begin 
	@rsubset :nmissing > 0
	@select :variable
        @rsubset :variable != Symbol("x26")
end) |> x -> vec(x[!, 1])
