Creating/Reading a complex string in R
Thanks for your pointer.
Is there any way in R how to replace " ' " with " /' " programmatically?
My actual string is quite lengthy, so changing it manually may not be
possible. I am aware of gsub() function, however not sure I can apply
it directly on my original string.
Regards,

CRAN binary, but no source
Hi All,
this is a CRAN question, so I am sorry if this is not the appropriate forum.
I noticed that there is at least one CRAN package that has a binary (OSX
Mavericks) for a version, that does not have any source package on CRAN. Or
at least I am unable to locate it. The package is Rglpk:
http://cran.r-project.org/web/packages/Rglpk/index.html
It offers a binary for 0.5-2, but there is no

Problems reading tab-delim files using read.table and read.delim
Hello,
I used read.xlsx to read in Excel files but for large files it turned out to
be not very efficient.
For that reason I use a programme which writes each sheet in an Excel file
into tab-delim txt files.
After that I tried using read.table and read.delim to read in those txt
files. Unfortunately, the results
are not as expected. To show you what I mean I created a tiny Excel sheet

Wishlist: write.delim()
Hi,
It would be great if someone would add write.delim() as an
adjunct to write.table(), just as with write.csv().
I store a lot of data in tab-delimited files and can read
it in easily with: read.delim("text.txt", as.is=TRUE)
and would love to be able to write it out as easily when
I create these files.
The obvious setting needed for write.delim() is sep = "\t",

read.delim()
I am reading in a very large file with names in it and R is truncating the number of rows it reads in. The separator in this file is a pipe '|' and so I use
dat <- read.delim('pathToMyFile', header= TRUE, sep='|')
It turns out that it is reading up to row 61145 and stopping and I think I see why, but am not sure of the best solution to this problem. I see the name of

read.table() vs read.delim() any difference??
Hi,
I have a tab seperated file with 206 rows and 30 columns.
I read in the file into R using read.table() function. I checked the dim()
of the data frame created in R, it had only 103 rows (exactly half), 30
columns. Then I tried reading in the file using read.delim() function and
this time the dim() showed to be 206 rows, 30 columns as expected.

Creating/Reading a complex string in R
Try:
String = '<html>
<head>
<script type="text/javascript" <script type="text/javascript">
mystatement(\'current\', {\'pac\':[\'\']});
mystatement;'
To embed a single ' mark in a string delimited by ' marks, you must
"escape" them by prefixing them with a back-slash \.

The try() function with read.delim().
I have written a function which reads data from files using read.delim
().
The names of these files are complicated and are built using arguments
to the wrapper function. Since the files in question may or may not
exist, I thought to enclose the read.delim() call in a try():
file <- <complicated expression>
temp <- try(read.delim(file))

Inconsistency, may be bug in read.delim ?

I stumbled into beheaviour of read.delim which I would consider a bug

read.delim very slow in reading files with lots of columns
Hi,
I am trying to read a tab-delimited file into R (Ver. 2.8). The machine I am using is 64bit Linux with 16 GB.
The file is basically a matrix(~600x700000) and as large as 3GB.
The read.delim() ran extremely slow (hours) even with a subset of the file (31 MB with 6x700000)
I monitored the memory usage, and found it constantly only took less than 1% of 16GB memory.
