[R] How to read.table with “Hebrew” column names (in R)?

(I am reposting this question after a few months without a solution...)


Hi all,

I am trying to read a .txt file, with Hebrew column names, but without
success.

I uploaded an example file to: http://www.talgalili.com/files/aa.txt

And tried the command:

read.table("http://www.talgalili.com/files/aa.txt", header = T, sep =
"\t")

This returns me with:

  X.....ª X...ª...... X...œ....
1      12          97         6
2     123         354        44
3       6           1         3

Instead of:

אחת שתיים   שלוש
12  97  6
123 354 44
6   1   3


 Trying to use something like:

read.table("http://www.talgalili.com/files/aa.txt",fileEncoding
="iso8859-8")

Has resulted in:

 V1
1  ?
Warning messages:
1: In read.table("http://www.talgalili.com/files/aa.txt", fileEncoding
= "iso8859-8") :

  invalid input found on input connection
'http://www.talgalili.com/files/aa.txt'
2: In read.table("http://www.talgalili.com/files/aa.txt", fileEncoding
= "iso8859-8") :

  incomplete final line found by readTableHeader on
'http://www.talgalili.com/files/aa.txt'

While also trying this:

Sys.setlocale("LC_ALL", "en_US.UTF-8")

Or this:

Sys.setlocale("LC_ALL",
"en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8")

Get's me this:

[1] ""
Warning message:
In Sys.setlocale("LC_ALL", "en_US.UTF-8") :

  OS reports request to set locale to "en_US.UTF-8" cannot be honored



My output for:

l10n_info()

Is:

$MBCS
[1] FALSE

$`UTF-8`
[1] FALSE

$`Latin-1`
[1] TRUE

$codepage
[1] 1252

And for:

Sys.getlocale()

Is:

[1] "LC_COLLATE=English_United States.1252;LC_CTYPE=English_United
States.1252;LC_MONETARY=English_United
States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252"

Finally, here is the > sessionInfo()

R version 2.10.1 (2009-12-14)

i386-pc-mingw32

locale:
[1] LC_COLLATE=English_United States.1255  LC_CTYPE=English_United
States.1252    LC_MONETARY=English_United States.1252 LC_NUMERIC=C
[5] LC_TIME=English_United States.1252

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

loaded via a namespace (and not attached):
[1] tools_2.10.1


Any suggestion or clarification will be appreciated.



Best,

Tal

[R] How to read.table with “Hebrew” column names (in R)?

I tried this on R 2.11.0 unstable (2010-03-07 r51225) using
encoding="UTF-8" and check.names=FALSE in read.table().
It seemed to basically work, except that the data.frame/matrix printing
routine wants to print the Unicode codes for the characters
in the names:

   > data1 <-
read.table("http://www.talgalili.com/files/aa.txt",
       header = TRUE, sep = "\t", encoding="UTF-8",
check.names=FALSE)
   > data1 # I see Unicode codes, presumably the correct ones
     <U+05D0><U+05D7><U+05EA>
<U+05E9><U+05EA><U+05D9><U+05D9><U+05DD>
   1                       12                                       97
   2                      123                                      354
   3                        6                                        1
     <U+05E9><U+05DC><U+05D5><U+05E9>
   1                                6
   2                               44
   3                                3 
   > colnames(data1) # I see Hebrew strings (in R the first starts with
aleph)
   [1] "???"   "?????" "????"
   > colnames(data)[1]
   [1] "???" 
   > strsplit(colnames(data)[1], "")[[1]][1]
   [1] "?"
   > data1[,"?????"]
   [1]  97 354   1

I'm writing this in Outlook in the English (American) locale
and the copy-n-paste from the R gui window to the Outlook window
of the Hebrew letters reversed the whole line of them (reversing
the characters in each name and the names in the line), which I
why I showed a subset of the names and a substring of the first name.

However, when I try to use lm() with this data.frame then I run into
trouble, which is probably the same problem as I see in the
data.frame printing:

   > lm(`?????` ~ `????`)
   Error: \uxxxx sequences not supported inside backticks (line 1)
