QUESTION
I have a scannerless parser grammar utilizing the CharsAsTokens faux lexer which generates a usable Java Parser class for ANTLR4 versions through 4.6. But when updating to ANTLR 4.7.2 through 4.9.3-SNAPSHOT, the tool generates code producing dozens of compilation errors from the same grammar file, as detailed below.
My question here is simply: Are scannerless parser grammars no longer supported, or must their character-based terminals be specified differently in 4.7 and beyond?
Update:
Unfortunately, I cannot post my complete grammar here as it is derived from FOUO security marking guidance, access to which is retricted by the U.S. government (I am a DoD/IC contractor).
The incompatible upgrade issue however is entirely reproducible with the CSQL.g4 scannerless parser grammar example referred to by Ter in Section 5.6 of The Definitive ANTLR 4 Reference.
As does my grammar, the CSQL example uses CharsAsTokens.java for its tokenizer, and CharVocab.tokens as its token vocabulary.
Note that every token name is specified by its ASCII character-literal equivalent, as in:

Answered 2021-Jun-07 at 00:17Try defining a GrammarLexer.g4 file instead of the GrammarLexer.tokens file. (You'd still using the options: { tokenVocab = GrammarLexer; } like you do if you create the GrammarLexer.tokens file} It could be as simple as:

I started looking into d3 and tried to create a histogram with 3D effect. Correctly calculated the position of all faces, but they are visible only cleanly and only in the browser's inspector. What's wrong with my code? (See method "updateChart")

QUESTION
I launched a week ago into my biggest google sheet formula and I am reaching the limits of what I can do. I usually always find the answers to my questions by searching a little, but not this time.
I have exported a list of projects since the start of the company in 2017, there are more than 9000 lines.
Inside there are lots of columns, but the ones that interest us are:
- start date
- organization
- state (draft, quotation or order)
- draft or quotation amount
- order amount
- status (dead, lost, canceled, provisional, open, reserved, active, completed)
In another sheet I wanted to show some columns based on some criteria but based on unique values from customers.
With as column:
- A / client
- B / income (sum of the order amount column if the status is different from lost, dead or canceled)
- C / number of contracts (number of orders if the status is different from lost, dead or canceled)
- D / number of draft and quotation (so if the state is equal to Draft or Quotation and the status is different from lost, dead or canceled)
- E / number of lost (when the status is equal to lost, dead or canceled)
- F / average amount per contract (B divided by C)
- G / conversion rate (C divided by C + D + E)
In addition to that, I have dedicated cells to choose dates, so that users of this table can sort by month and / or year (see screenshot).
I started by using the UNIQUE function in column A to output the customer list. I then made SUMPRODUCT in the other columns according to my criteria. But 6 columns x 600 rows of SUMPRODUCT, googlesheet takes 5 min to give me a result every time I change my dates ... So I looked around a bit and discovered the UNIQUE, FILTER and SUMIF mix.
To help me with that, I created columns at the end of my 1st table (see 1st screenshot) which will help me with my SUMIFS (SOMME.SI in French), there will only need to be the addition of each of the rows, with as criterion the UNIQUE of the 1st column and the dates. If I did that, it's because I couldn't do SUMPRODUCTs in ArrayFormula.
By trying a little I came up with a huge formula.

QUESTION
I have to calculate a lot of bootstrapped correlations (Pearson r). My knowledge of R (not to speak of writing my own functions) is limited. So far, I have only managed to calculate each bootstrapped correlation individually via boot::boot(), which is quite time intensive due to the high number of correlations.
How do I calculate several bootstrapped correlations at the same time?
Here is the code I've been working with successfully, i.e. calculating each correlation individually. This means I would have to repeat this code around 300 times, exchanging small parts of the code each time.
...ANSWER
Answered 2021-Apr-29 at 08:47Your bootPearson() function does not do what you presumably want it to do. Right now, it calculates seven different correlations but only returns the last one - everything else gets calculated and discarded. In R, functions only return the last result created in the function body. You may want to read up on how R functions work.
The solution is simple: just change bootPearson() to create and return a single object - namely, a vector of length 7 that contains the seven correlations you calculate. Concatenate them into one vector using the c() command:

QUESTION
ANSWER
Answered 2021-Apr-12 at 03:20In init() of View changing UITableView.appearance:
The most things that we are using in SwiftUI such as List or NavigationView, . . they are not pure SwiftUI and they are coming from UIKit, therefore we use UIKit code type for changing appearance. if you remember we should use such codes in UIKit. And when we use UITableView in init we are accessing to the class of UITableView UIKit, it means this change would apply to any View in our project which they are using List.
The best way is the way you are doing, setting transparent Color, then changing Color from SwiftUI in body! that is the most convenient way.
QUESTION
First question here, so apologises for any faux-pas. I have a dataframe in R of 657 observations with 4 variables. Each observation is a speech or interview by the Australian Prime Minister. So the variables are:
- date
- title
- URL
- txt (full text of the speech/interview).
I'm trying to turn that into a corpus in Quanteda
I first tried corp <- corpus(all_content) but that gave me an error message

Answered 2021-Apr-08 at 17:23It's hard to address this problem exactly, because there is no reproducible example of your data.frame object, but if the structure contains the variables you list, then this should do it:
