Weiqiang Zhuang commented on SPARK-10913:
-----------------------------------------
I think they are different issues. If I understand, SPARK-7499 deals with cases
where inside a function of a DataFrame, the column of the DataFrame may be
referenced by the name. For example, the select function: select(df,
Sepal_Width). Where the first input is the DataFrame and the second input is
one of the columns of the DataFrame.
This issue, however, is to implement the attach() function which will allow to
use the object (any column of a DataFrame) by the name without specifying again
which DataFrame the object associated with. For example:
attach(df)
head(Sepal_Width)
summary(Sepal_Width)
detach()
The head() and summary() functions know exactly where to find the object for
Sepal_Width without specifying it as df[, "Sepal_Width"].
