RSQLite problems
Hi, I'm experimenting with using (R)SQLite to do data management. Here are
two little problems that I've encountered:
1. The presence of ',' in string values causes trouble since ',' is also the
delimiter used in the SQL statement.
2. A newline '\n' line attached to the last string value of each row.
Some examples:

Why does 'exists' need a quoted argument?
Some functions in R need quoted arguments. Consider this list:
help(rm)
rm(a)
is.na(a)
get("rm")
exists("rm")
Can someone explain why 'get' and 'exists' require quoted object names?
Would it make sense (more consistency) to have these functions check to see if the first argument is a string, and if not, then 'substitute' it? Intuitively,

RMySQL fetch defaults to N=500?
It appears that fetch() gets only the first 500 rows by default. I
don't see this in the documentation, but
timeinfo <- fetch(rs)
gets only 500 rows where
timeinfo <- fetch(rs,n=-1)
gets (correctly) 736 for the same query. Is this an undocumented
feature? I played with this data for an alarming amount of time
before I realized that I was missing a third of the data. I

Problem with save or/and if (I think but maybe not ...)
Hi,
I recently discovered the R program and I thought it could be useful to me.
I have to analyse data saved as .Px file (x between 0 and 8 - .P0 files have
18 lines at the beginning that I have to skip). New files are generated
everyday.
This is my strategy :
In order to analyse the data, I first want to copy the new data in a
database in MySQL (which already contains the previous data).

ROracle/DBI problem with dbExecStatement on RH Linux
Hi,
first thanks to Sunny Ho (and David James for the pointer) for resolving
the problem of the empty rows returned from ROracle.
However, I have a problem still:

Database newbee problem...
Hi all,
This is a potentially very stupid question about MySQL <-> R
interaction, but I have not been able to solve it.
I'm just trying to connect R to my MySQL databse, and gets this:

MySQL server has gone away
I'm running 2.0.17 and I'm still seeing a decent amount of "MySQL
server has gone away" errors, despite having multiple hosts defined in
my auth userdb 'connect'. This is Debian Lenny 32-bit and I'm seeing
the same thing with 2.0.16 on Debian Squeeze 64-bit.
E.g.:

problem with cdr_odbc
Hi,
Has anyone made a successfull instalation of cdr_odbc??
I've install unixODBC-2.2.8 (made my own RPM) and then built the module.
I'm trying to send the cdrs to a M$ SQL server. The sql connection
works because I can do any query via isql.
When I do the calls I get the following output on the asterisk console:

installing RMySQL
Hi, I have struggled to re-implement the RMySQL package after upgrading

Sgeostat module
Dear Users,
I use Sgeostat to calculate co variogram (function est.variogram with two
variables).
If i inverse the 2 variables in the functions, the co variogram change!
Normaly it is symmetric, isn't it?
Someone could me explain why, or give me an idea to calculate co variogram
in a easy way...
Thanks in advance

plotting overlapping data points
I am just learning to use R. The data from my current project are
integer-valued. I am able to create scatterplots, but I would like to
have some indication on the plots when multiple data points overlap at
the same x-y coordinate. SPSS uses 'petals', and other packages use
jitter. Are there similar options in R? I have not been able to find
any in the documentation.
Thanks very much,

Importing many files
Hello Cracks,
we want to import 10 x 365 files containing each 7 variables with 1211
rows. The filenames end with numbers from 1 to 365. We tried a for loop
to import using read.table but we couldn't create the r objects within
the loop. We want each file in an own r-objekt (matrix).
Does anyone know what can be done?
Thanks, Felix
