Seeing Global Workspace and dealing with attach and detach

In general, creating variables while attached leads to problems such as you describe. Normally the recommendation is to avoid the use of attach and detach entirely in favor of explicit reference to the data frame using [[]], [,], $, and the data= argument supported by many functions.

Hi,

When writing a script, I often start with:

library(ISwR)
attach(thuesen)

Then write some more code, testing it as I write to see if it runs.

Then, at the end, a final:

detach(thuesen)

However, what happens is that I often get errors, which cause an
attach, but
no subsequent detach. Now, I can fix the problem at the console window
with
several:

detach(thuesen)
detach(thuesen)
detach(thuesen)
detach(thuesen)
detach(thuesen)

Until they are finally all closed.  Two questions:

1. What is a more efficient method?

2. What is the command again for viewing the global workspace?

D.
