I am faced with rewriting an Excel project in R. I see a table in which a cell {= TABLE (F2, C2)} is shown. I understand how to create a Table like this (What-If Analysis, Data Table...).
As I have to understand this to rewrite in R, how can I find the original formula which stands behind that cell?
EXAMPLE: I have created a Data Table as shown here and the sheet looks like this:
In my case, I don't know how the sheet was created, and I want to know the initial formula. Now this is shown as {=TABLE(,C4)}.
(In the example I know the answer, it is in the cell (D10), but where is reference for this cell in Data Table?)
I'm using Excel 2007 but have no reason to believe things differ in other versions.
#Stanislav was right to reject my comment suggestion that TABLE was a name; it is an EXCEL function. But it is a very strange function :-}
There isn't any help on the TABLE function in the local help, it isn't listed in "List of worksheet functions (alphabetical)".
You can't manually enter or edit the TABLE function; error "That function is not valid".
Copy/Pasting cells containing the TABLE function pastes their values, not their formulae, even when you specify Paste Special > Formulas
You can't insert rows/columns immediately above/left of cells containing the TABLE function; error "Cannot change part of a data table".
Pace #pnuts using Formulas > Formula Auditing cells containing the TABLE function shows no precedents and no cells show them as dependents. Although in a VBA sheet auditing tool which I use the Range.DirectDependents Property finds the "formula range" dependent on the "margin" cells containing the formulas, but not those containg the values (see below for explanation of those terms).
I haven't been able to find anything I regard as decent documentation of TABLE(). I have found lots of illustrations of how to produce and use that function, but nothing clearly specifying the arguments and result. The best I've found is https://support.office.com/en-us/article/Calculate-multiple-results-by-using-a-data-table-e95e2487-6ca6-4413-ad12-77542a5ea50b. I'd be pleased if anyone can point me to better documentation.
I deduce the bahaviour as described here:
TABLE(Rowinp,Colinp) is an array formula in a contiguous array of cells. I'll refer to that contiguous array as the "formula range" of the data table.
The cells immediately above/left of the formula range are also part of the data table, even though they do not contain a TABLE() function and can be edited; I'll refer to those cells as the "margins" of the data table.
Rowinp and Colinp must be blank or references to single cells.
Rowinp and Colinp must be different (or error "Input cell reference is not valid"), they must not both be blank.
The values in the formula range are calculated by taking formula(s) from the margin(s) and substituting references to Rowinp and/or Colinp with values from the margin(s).
There are three mutually exclusive possibilities, corresponding to Rowinp blank or not.
TABLE(Rowinp, ) Colinp blank. The formula is that in the left margin of the same row with instances of Rowinp replaced by values from the upper margin of the same column.
TABLE( , Colinp) Rowinp blank. The formula is that in the top margin of the same column with instances of Colinp replaced by values from the the left margin of the same row.
TABLE(Rowinp, Colinp) Neither blank. The formula is that in the cell at the intersection of the left and top margins with instances of Rowinp replaced by values from the upper margin of the same column and instances of Colinp replaced by values from the the left margin of the same row.
I think that should let you work out what the effective formula is in each cell of the formula range.
But I wouldn't be surprised to learn that any of the above is wrong :-0
I welcome pointers to anything more authoritative.
I think in your example the F2 and C2 are effectively only the addresses of parameters for a function (TABLE) where that may be located anywhere, with the associated formula in the table's top left cell.
So I suggest go to C2, FORMULAS > Formula Auditing and click Trace Dependents, repeat for F2 and see where the arrows converge.

I work a lot with the new tables collect command in stata 17. Does anybody know how to get the confidence interval in one cell in the table vs. One column for lower bound and one column for the upper bound estimate?
Alternatively a quick fix in word (or excel though my final document is word. Saving the output in excel takes so long)
Is I see it there is no option to put it in one column, so maybe a layout work around?
From the stata documentation of the collect command, the quick start mentions
table (colname) (result), command(_r_b _r_ci: regress y x1 x2 x3). You should be able to use collect with it, but without a minimum reproducible example of your specific case, it is hard to verify if this works as intended in your case. For the general idea of a minimum reproducible example please see here and for specific advice on how to create a minimum reproducible example please see here.
Here is a general example that uses table, collect and putdocx to create a word document to get the confidence interval in one cell:
use https://www.stata-press.com/data/r17/nlsw88.dta
table (colname) (result), command(_r_b _r_ci: regress wage union occupation married age)
collect layout (colname) (result)
putdocx begin
putdocx collect
putdocx save Table, replace
forest area to the I want to add a column name (say ForestAreaPerPopn) to find the ratio of forest area to the population(represented by variable Total below) residing. The data contains the following variables and their values.
How can I add a column named ForestAreaPerPopn in Table****ForestAreaPerPop (shown below) so that the column contains the data calculated as ratio of forest area to Total.
Too long for a comment.
You have a couple of problems. First, your column names have spaces and other special characters. This is allowed but creates all kinds of problems later. I suggest you do something like:
colnames(ForestAreaPerPop) <- gsub(' |\\(|\\)', '_', colnames(ForestAreaPerPop))
This will replaces any spaces, left or right parens in the colnames with '_'.
Then, something like:
ForestAreaPerPop$n <- with(ForestAreaPerPop, Forest_Area_in_ha/Total)
should give you what you want.
Some advice: long table names and column names may seem like a good idea, but you will live to regret it. Make them short but meaningful (easier said than done).
I have tens of thousands of rows of unstructured data in csv format. I need to extract certain product attributes from a long string of text. Given a set of acceptable attributes, if there is a match, I need it to fill in the cell with the match.
Example data:
"[ROOT];Earrings;Brands;Brands>JeweleryExchange;Earrings>Gender;Earrings>Gemstone;Earrings>Metal;Earrings>Occasion;Earrings>Style;Earrings>Gender>Women's;Earrings>Gemstone>Zircon;Earrings>Metal>White Gold;Earrings>Occasion>Just to say: I Love You;Earrings>Style>Drop/Dangle;Earrings>Style>Fashion;Not Visible;Gifts;Gifts>Price>$500 - $1000;Gifts>Shop>Earrings;Gifts>Occasion;Gifts>Occasion>Christmas;Gifts>Occasion>Just to say: I Love You;Gifts>For>Her"
Look up table of values:
Zircon, Diamond, Pearl, Ruby
Output:
Zircon
I tried using the VLOOKUP() function, but it needs to match an entire cell and works better for translating acronyms. Haven't really found a built in function that accomplishes what I need. The data is totally unstructured, and changes from row to row with no consistency even within variations of the same product. Does anyone have an idea how to do this?? Or how to write an OpenOffice Calc function to accomplish this? Also open to other better methods of doing this if anyone has any experience or ideas in how to approach this...
ok so I figured out how to do this on my own... I created many different columns, each with a keyword I was looking to extract as a header.
Spreadsheet solution for structured data extraction
Then I used this formula to extract the keywords into the correct row beneath the column header. =IF(ISERROR(SEARCH(CF$1,$D769)),"",CF$1) The Search function returns a number value for the position of a search string otherwise it produces an error. I use the iserror function to determine if there is an error condition, and the if statement in such a way that if there is an error, it leaves the cell blank, else it takes the value of the header. Had over 100 columns of specific information to extract, into one final column where I join all the previous cells in the row together for the final list. Worked like a charm. Recommend this approach to anyone who has to do a similar task.
I am using the tabular() function to produce tables in r (tables library).
I want to compute CI's from the data in the output (let mytable be the output from tabular()). Simple enough I thought, except when I go to call a value from the matrix, I get the error Error in mytable[1, i] - 1 : non-numeric argument to binary operator. I thought this was odd, as when I call up a particular cell of the matrix (where as.matrix returned true for mytable), for example mytable[1, i] for some i, I get an interger. I then do the as.list for mytable and get true also, so I am not sure what this means. I guess the tabular() function stores the results as a special kind of matrix.
I am only trying to pull out the mean,sdev, and n, which I am able to just by typing the cell location, for example mytable[1, i] would return an 86. However, when I try to call up the value in qt(.975,df=(mytable[1,i]-1)) for example, I get the error above. Not sure really how to approach this except to manually enter the values into another matrix (which I would like to avoid). Or, if I can compute CI's directly in the tabular() function that would work also. Cheers.
I shall quote for you the Value section of the documentation on the function ?tabular:
An object of S3 class "tabular". This is a matrix of mode list, whose
entries are computed summary values, with the following attributes:
rowLabels - A matrix of labels for the rows. This will have the same
number of rows as the main matrix, but may have multiple columns for
different nested levels of labels. If a label covers multiple rows, it
is entered in the first row, and NA is used to fill following rows.
colLabels - Like rowLabels, but labelling the columns.
table - The original table expression being displayed. A list of the
original format specifications are attached as a "fmtlist" attribute.
formats - A matrix of the same shape as the main result, containing NA
for default formatting, or an index into the format list.
As the documentation says, each element of the matrix is a list. If your tabular object is called tab type tab[1,1] and you should see a list containing one of your table values. If I wanted to modify that value, I would probably do something like:
tab[1,1]$term <- value
just like you would modify values in any other list.
Type attributes(tab) and you'll see the items listed above, containing a lot of the formatting information and row/col headers.
I've perused the Stack Exchange list of sites, and I can only think that SO is the right place to ask this (I saw a few excel questions, at least).
I have an array of values Sheet1.B3:B9. On another sheet, I'm trying to get a random value from one of those cells.
I suppose it has to be something with the RANK() function, but I'm grasping at straws.
How can I get the value of a random cell in that range?
In LibreOffice Calc to get a random cell between cells B3 and B9 of Sheet1 you can do:
=INDEX(Sheet1.B3:B9, RANDBETWEEN(1,5))
In Excel, this will give random lookup into the range
=INDEX(Sheet1!$B$3:$B$9,INT(RAND()*7)+1)
Or you can give your source data range a name
=INDEX(RandDataSource,INT(RAND()*ROWS(RandDataSource))+1)
Don't know if it applies to Openoffice
