OCI adapter slowdown on dictionary access
Hi,
after some experience with Rails on MySQL databases I gave it a try on one
of our larger Oracle database.
I was facing a problem when Rails tried to detect the columns for a
model/table. The appropriate statement ran about 1 min which led to a
timeout.
Our Oracle guru told me to analyze the SYSTEM schema. After that hadn''t
helped, he said the only remaining chance is to use a

using a string as the formula in rlm
Hi,
I am trying to build a series of rlm models. I have my data frame and
the models will be built using various coulmns of the data frame.
Thus a series of models would be
m1 <- rlm(V1 ~ V2 + V3 + V4, data)
m2 <- rlm(V1 ~ V2 + V5 + V7, data)
m3 <- rlm(V1 ~ V2 + V8 + V9, data)
I would like to automate this. Is it possible to use a string in place
of the formula?
I tried doing:

What I have is two sets of fields in a record, set A and set B. Both

PayPal WSDL API on Rails anyone ?
Hi !
Has anyone connected to the Mass Pay API of PayPal using Rails ? I
need to do this for a customer, and I wanted to know how easy/hard it
was. I have no experience using SOAP, WSDL, etc.
I saw soap4r[1] on the RAA[2]. This is probably what I''ll need to
use. One question I haven''t answered yet is whether soap4r will
accept PayPal''s certificates ?
Thanks for any

difference of two data frames
Hello
I have 2 data frames DF1 and DF2 where DF2 is a subset of DF1:
DF1= data.frame(V1=1:6, V2= letters[1:6])

How do I create a new data frame of the difference between DF1 and DF2
newDF=data.frame(V1=4:6, V2= letters[4:6])
In my real data, the rows are not in order as in the example I provided.

Me parece que podrías investigar si Scribus puede generar e insertar la
