[R] dbWriteTable(con, access_log, overwrite = F).....

2012-01-16 Thread Poul Kristensen
I am new to R.

My goal is to make a crosstable from a Apache access.log, which I want
to load into PostgreSQL database at first to
learn more abour R and DBI and datatypes. When the I have got the
access.log in the database I will try to make the
crosstable!

Trying to load the Apache access.log into PostgreSQL I get an error.

dbWriteTable(con, access_log, overwrite = F);

returns

Error in .Internal(is.vector(x, mode)) : 'x' is missing?

Thanks

Poul

[R] unable to find an inherited method for function "make.db.names", for signature "character", "missing"

2012-01-17 Thread Poul Kristensen
Hi !

I am new to R and I am using Rstudio on Linux.

Have I missed some library() ?

and if so does anyone have the time to write which?

I am trying to create some PostqreSQL tables from comma separated files.

I am a bit surpriced that character is a problem. The missing value
could be NULL.


Thanks

Poul

Hello Catarina Maia

I'm a beginner too!

And I ask questions and people are answering very kindly.
>From what I know up til now is that R is a competitor to the
very expensive SAS statistical software. R is free to use and is
developed by professors and Ph.d's.
As of my interest right now is R's interacting with databases like
PostgreSQL(free and opensource) and Oracle(_not_ free) getting
data in and out.
Furthermore I am trying to make R usefull handling Apachelogs.
R does not consume as much machine resources(RAM,CPU) as SAS software as
is faster handling "Big data".

I hope you are encouraged to stay with the list.

Regards
Poul
