problem with toString
Hi,
I am using R 1.5.1 under Windows 2000. I have a problem with the function toString: It seems not to work for longer
vectors as expressions.
This example works well:
q1<-expression(c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15))
toString(q1)
I get:
"c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)" => OK
But this one does not:

Convert a column of numbers to a column of strings
Hello,
Please excuse me if this question has been asked before. I'm new to R, and
have been trying to google the answers without any success.
I would like to convert a set of date and time into R date-time class. Right
now, the dates and times are in integer format, so I first need to convert
them into string, and then to R date-time using strptime. However, I have a
problem converting them

Bug: time complexity of substring is quadratic as string size and number of substrings increases
Hi all, (and especially hi to Tomas Kalibera who accepted my patch sent
yesterday)
I believe that I have found another bug, this time in the substring
function. The use case that I am concerned with is when there is a single
(character scalar) text/subject, and many substrings to extract. For example
substring("AAAA", 1:4, 1:4)
or more generally,
N=1000

Help with replacing a substring in a string
Dear R Users,
I am trying to replace a substring in a string with something else.
For example:
if we have "abc.degg.hijk"
I would like to replace all the "." with a SPACE to become
"abc degg hijk"
I have tried the replace.substring.wild function in the Hmisc package but get this error:

[LLVMdev] __time_t type instead of __time64_t inwin32/TimeValue.cpp
Replace __time_t with time_t in my question. I've compiled function:
std::string TimeValue::toString() const {

//hb: __time64_t ourTime = this->toEpochTime();
time_t ourTime = this->toEpochTime();

RW 0.64.2 substring() string truncation?
Hi,
(First, apology for my earlier incorrectly addressed "subscribe"
post.)
Can somebody tell me what exactly is going on below. Basically, I am
running into some kind of "string truncation" problem when I try
to get a substring starting past the 8192nd character (see sample
session below). There doesn't appear to be any problem creating the

Wishlist: Sweave: allow line breaks after forward slashes (PR#9443)
Full_Name: Arne Henningsen
Version: 2.4.0
OS: Linux
Submission from: (NULL) (134.245.140.242)
Sweave does not allow line breaks after forward slashes ("/"). This might lead
to a long "substring" of a command that cannot be wrapped. Hence, Sweave either
keeps this long "substring" in the current line and produces a too long line or
it moves the entire

string problems in R
Hello all
I have been working on my thesis using R. I am a newbie to R and met a problem
that bothered me for a while due to my lack of acquaintance of R.
I am using R to query from SQL. I got a list of crsp_fundno of G-style mutual
funds which is still alive. I use the following codes and got what I want:

locate substring in the string it belong to
Hi R users,
I am trying generate the indices for locating a in the string it come from.
Given the length of the string, it will take too long using the combn() for
further comparison. I am wondering if R has any built-in function for this
purpose.
To make it concrete:
this.substring="cc"
this.string="ccc"
start.location=1,2
end.location=2,3
Thanks in advance,

write.csv / string extraction and field limits
Hello,
I have a peculiar problem which I am hoping I can get help on.
I am using the write.csv command to write a matrix structure to a file,
which I later read in excel. The command works quite well for most strings
and numerical values in the matrix structure.
However, I have found that when a field in the matrix contains a string of
long length, when the matrix is finally written the file

how to count the total number of (INCLUDING overlapping) occurrences of a substring within a string?
Last one for you guys:
The command:
length(gregexpr('cus','hocus pocus')[[1]])
[1] 2
returns the number of times the substring 'cus' appears in 'hocus pocus'
(which is two)
It's returning the number of **disjoint** matches. So:
length(gregexpr('aa','aaa')[[1]])
[1] 1
returns 1.
**What I want to do:**
I'm looking for a way to count
