[R] need help with excel data

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.
