create dummy variables by for loop
HI, Dear R community,
I try to create 100 dummy variables like the following:
ack$id_1 <- (ack$ID==1)*1
ack$id_2 <- (ack$ID==2)*1
..
.
ack$id_100 <- (ack$ID==100)*1
I used the following codes:
for(i in 1:100){
ack$id_[i] <- (ack$ID==i)*1
}
But only one column is created, can anyone help me?
Thanks a lot!

Efficient way to code using optim()
Hi all,
I am trying to estimate a simple logit model.
By using MLE, I am maximizing the log likelihood, with optim().
The thing is, each observation has different set of choice options, so I need a loop inside the objective function,
which I think slows down the optimization process.
The data is constructed so that each row represent the characteristics for one alternative,
and CS is a

DB Migrations & Column Order
Hello,
I created a table and about 10 migrations down the line I decided that
I needed to add an ID column (this was actually a table for a has_many
:through and I recently realized that it needs an ID column, unlike
HABTM tables). I am a big perfectionist and I frequently run "SHOW
COLUMNS IN table;", so I naturally expect to see the "id" column the
first one listed. However,

Migrations - add_column :default=>true, :null=>false
This seems pretty brain dead:

Error: ERROR: column "notify_on_create" contains null values
: ALTER TABLE types ALTER notify_on_create SET NOT NULL
Why doesn''t Rails set the new column to true, as it''s supposed to
default to? I tried :default=>1 as well (same

[PATCH] Enhance vms display
It can be quite hard to manage a pool of 40-50 VMs without informations about the OS running, the contact (which is the only one to know when the vm can really be destroyed) or an End Of Life date. This patch add those fields, and rework a little the VM list view, in order to show gracefully those new fields. It has been made at the expense of UUID, Total Run Time & Load fields. Since those
