I am fascinated by lazy evaluation mechanism provided by delayedAssign. Like
delayedAssign(foo, {
Sys.sleep(1) # or any other time consuming operations
1
}
Time consuming operations will be evaluated only if object foo is used.
But when I try:
foo - list()
foo$bar - 1
Hi,
Despite OS is not provided, we can guess it is Windows, since Tinn-R works only
on Windows. The error message is quite clear, I think: R must start a socket
server in order for Tinn-R to communicate with it. Did you look at
?startSocketServer in the svSocket package? Then, you would have a
delayedAssign(foo$bar, 2)
foo$bar # 1
`foo$bar` # 2
Yes, you assign to the new variable `foo$bar`, not to bar component of the foo
variable!
You can use an environment for doing what you want:
e - new.env()
e$bar - 1
delayedAssign(bar, 2, assign.env = e)
e$bar
But notice also the

I am slowly getting enough of wireframe() from the package lattice, as
it is to complicated for what I need and does not really do what I

I have a very long data frame (50 years, more than 1.5 million rows) of daily

Recent changes include the following.
Changes in version 3.14-2 (2014-02-26)
* latex.default: improved logic using new function in Misc: latexBuild
* latex.default: fixed bug with ctable=TRUE with no caption by
removing default label
* latex.default: improved formatting for insert.top
Changes are listed below.
NOTE: The next release of rms will replace the survfit.formula function
with a new function named npsurv (nonparametric survival estimates) so
as to not conflict with the survival package. This is a

Figured it out: I created two ts() objects, one for each parameter, then
plotted them using cbind. Just need to tweak how the dates display on the x

If you change the last line of the code:

The problem is in the order of the colnames/rownames in each of the datasets.
