85, 70 To 75, 83 Case 2, 4, 6, 8 Debug.Print "Even numbers" Case 1, 3, 5, 7 Debug.Print "Odd numbers" The following is an example of using multiple strings: Out of curiosity, why does using keyword arguments violate type stability? I'm not sure about the naming. Googling "remove duplicate column after join" yields > 250K results so I don't think it's an invalid case, even if rare. !non is kind of silly right from the beginning. In R it's idiomatic to do df[complete_cases(df),]. if I did? The use case is if you have a big dataset with thousands of rows and hundreds of columns, some of which have Nulls, and you want to do an operation on a subset of the columns in a statistical function (lm EDIT: I see that lm already deals with Nulls) or plot it. I think this will be helpful in that it unifies the behavior patterns of iscomplete and isunique and lets us completely start from scratch rather than carry over one of the two different behaviors of complete_cases and complete_cases!. I imagine users would begin running @assert iscomplete(dt) && isunique(dt) as a nice pre-check when working with new datasets. @mkborregaard would that be an acceptable compromise to make when specifying specific columns to check? Data tables are not exactly like arrays, their dimensions are not really symmetric so we don't always need to support operations for both rows and columns. Using only amsmath package, the environement aligned allows you to use as many columns as you want : Thanks for contributing an answer to TeX - LaTeX Stack Exchange! the reverse) is always used.

What's the etiquette for addressing a friend's partner or family in a greeting card? I am trying to evaluate eligibility based on the value of several combinations in each record. Il controllo passa quindi all'istruzione che segue End Select.Control then passes to the statement following End Select. Right now, completecases satisfies the first, and the inverse of nonunique, . a DataTable . isuniquerow? Learn more. Learn more. update publishers set That wouldn't change the return type as it did for my earlier suggestion, and I think everyone would immediately intuit what completecases(dt, on={Int, Symbol, Vector{Int}, Vector{Symbol}} means that the function is only checking either the individual (bracket free) column or the series of columns in the array. The latter should work in a more general setting. That would make unique and isunique quite different I think. Is it important for a ethical hacker to know the C language in-depth nowadays? Aliases. If you specify that you want to check row-wise or col-wise, then you'll break from that "single value" convention and get the boolean indices for all rows and columns as everyone (I think?) If a person is dressed up as non-human, and is killed by someone who sincerely believes the victim was not human, who is responsible? Thanks to both of you for the explanations on the type insecurity. Filtering with multiple conditions in R is accomplished using with filter() function in dplyr package. data: A data frame.... Specification of columns to expand. In the discourse post (https://discourse.julialang.org/t/is-there-a-dropna-for-dataframe/1777/19) , @mwsohn suggested some code that could form a useful basis for a PR. I probably would find a different way to express my ideas. I'm trying to use the cases environment to show an arbitrary equation. We can have multiple case conditions on one line. Two PhD programs simultaneously in different countries. is.na, na.omit, na.fail. But I noticed that it only allows me to use 2 columns. I tried not to make too many assumptions about user patterns when thinking about isunique and iscomplete behavior. I think we all have our own assumptions about what kind of patterns are common and justifiable, but one justification I could think of for isunique on columns is what if someone wanted to do several outer joins and confirm that they hadn't introduced duplicate columns? @mkborregaard could you apply the changes (returning a view and only checking the appropriate columns for complete cases) to dropnull in #39? We simply use the comma to separate them: Case Is > 85, 70 To 75, 83 Case 2, 4, 6, 8 Debug.Print "Even numbers" Case 1, 3, 5, 7 Debug.Print "Odd numbers" The following is an example of using multiple strings: Out of curiosity, why does using keyword arguments violate type stability?
