Hi all! Sorry to bother you, I am trying to learn some R via coursera courses and other internet sources yet haven?t managed to go far And now I need to do some, I hope, not too difficult things, which I think R can do, yet have no idea how to make it do so I have a big set of data (empirical) which was obtained by my colleagues and store at not convenient way - all of the data in two cells of an excel table an example of the data is in the attached file (the link) https://drive.google.com/file/d/0B64YMbf_hh5BS2tzVE9WVmV3bFU/view?usp=sharing so the first column has a number and the second has a whole vector (I guess it is) which looks like ?some words in Cyrillic(the length varies)? and then the set of numbers ?12*23 34*45? (another problem that some times it is ?12*23, 34*56? And the number of raws is about 3000 so it is impossible to do manually what I need to have at the end is to have it separately in different excel cells - what is written in words - | 12 | 23 | 34 | 45 | Do you think it is possible to do so using R (or something else?) Thank you very much in advance and sorry for asking for help and so stupid question, the problem is - I am trying and yet haven?t even managed to install openSUSE onto my laptop - only Ubuntu! :) Thank you very much!
Dr. Polanski, I would recommend something else. Given the messy nature of
your data I would suggest using a language like Python or Perl to extract
it to an appropriate format. Python has good regular expression support
and unicode support. If you can save your data as a csv file or even text
line by line then it would be possible to write some code to read the file,
match the lines with a simple regular expression, and then spit them back
out as a csv file which you could read into R.
I realize that this means learning a new language or finding someone with
the requisite skills by I would recommend that over attempting to use R's
text processing.
Collin.

Try asap utilities (Home and Student edition), http://www.asap-utilities.com/index.php. When installed it will look like this in Excel, Select Columns & Rows and then #18. If that is not helpful, then DigDB, http://www.digdb.com/, but this one requires a subscription. It will also split columns. You may have to do some 'cleaning' of individual cells, such as removing leading and/or trainling spaces. A lot of this can be one with the ASAP Utilities 'Text' pull down menu.

I think R is quite capable of doing this. You would have to learn a
comparable number of fiddly bits to accomplish this in R, Python or Perl.
That is not to say that learning Perl or Python is a bad idea... but in
terms of "shortest path" I think they are of comparable complexity.
All
three languages support regular expressions, which would be the key bit of
knowledge to acquire regardless of which tool you use.
Other fiddly bits might involve handling the cyrillic strings as data,
though you did not convey a desire to retain that information.
One way (not extracting cyrillic text):
library(XLConnect)
DF <- readWorksheetFromFile( "exampX.xlsx", sheet="examp"
)
pattern <- "^.*(\\d+) *\\* *(\\d+)[^\\d]*(\\d+) *\\* *(\\d+).*$"
idx <- grep( pattern, DF[[2]] )
dta <- sub( pattern, "\\1,\\2,\\3,\\4", DF[[2]][idx])
dtamatrix <- apply( do.call( rbind
, strsplit( dta, "," ) )
, 2
, as.numeric
)
extracted <- data.frame( V1=DF[[1]][idx], dtamatrix )

The following is one way to parse your file using R (using R-3.1.2 on Windows in a US English locale). I downloaded it from Google Docs in tab-separated format. I could not get read.table() to do the job, but I don't completely understand the encoding/fileEncoding business there.> file <- "exampX.xlsx - examp.tsv" # the name Google Docs suggested > lines <- readLines(file, encoding="UTF-8")Warning message: In readLines(file, encoding = "UTF-8") : incomplete final line found on 'exampX.xlsx - examp.tsv'> fields <- strsplit(lines, "\t") > txt <- vapply(fields, function(x)x[2], "") # 2nd field of each line > nmbrs <- regmatches(txt, gregexpr("[[:digit:]]+(\\*[[:digit:]]+)*", txt)) > lines[16:20][1] "1.97\t?.?. 11 35*46 27*46" "1.61\t????? 9 31*36 29*45" [3] "1.17\t?.?. 4 37*29 39*30" "1.54\t??? 9 31*39 30*38" [5] "1.73\t????? 6 32*39 29*39"> nmbrs[16:20][[1]] [1] "11" "35*46" "27*46" [[2]] [1] "9" "31*36" "29*45" [[3]] [1] "4" "37*29" "39*30" [[4]] [1] "9" "31*39" "30*38" [[5]] [1] "6" "32*39" "29*39" If you want to split those "x*y" into "x" and "y" you can use the pattern "[[:digit:]]+" instead of the one I used.

Hi Dr Polanski,
I would recommend you do this in excel seeing as you know how to work with
excel. You can use excel to put different parts of a cell into another cell.
For example if cell A1 is 12*23 34*45
And you want "12" in a separate cell (say cell A2) go to cell A2 and
type: =LEFT(A1,2)
This will extract the first 2 characters from the left.
To extract "45" you would type: =Right(A1,2)
To get 2 characters starting at position 4 you would type: =MID(A1, 4,2)
Which will give you 23.
Hope this helps.

Subject: [R] need help with excel data
Hi all!
Sorry to bother you, I am trying to learn some R via coursera courses and other
internet sources yet haven?t managed to go far
And now I need to do some, I hope, not too difficult things, which I think R can
do, yet have no idea how to make it do so
I have a big set of data (empirical) which was obtained by my colleagues and
store at not convenient way - all of the data in two cells of an excel table an
example of the data is in the attached file (the link)
https://drive.google.com/file/d/0B64YMbf_hh5BS2tzVE9WVmV3bFU/view?usp=sharing
so the first column has a number and the second has a whole vector (I guess it
is) which looks like ?some words in Cyrillic(the length varies)? and then the
set of numbers ?12*23 34*45? (another problem that some times it is ?12*23,
34*56?
And the number of raws is about 3000 so it is impossible to do manually
what I need to have at the end is to have it separately in different excel cells
- what is written in words - | 12 | 23 | 34 | 45 |
Do you think it is possible to do so using R (or something else?)
Thank you very much in advance and sorry for asking for help and so stupid
question, the problem is - I am trying and yet haven?t even managed to install
openSUSE onto my laptop - only Ubuntu! :)
Thank you very much!
