Plot an ols() call from Design
Dear users,
I am attempting to plot an ols() call from the Design package, by
following the procedure explained by Harald Baayen in his 2008 book
'Analyzing linguistic data. A practical introduction to statistics
using R', page 175-181.
I've attached my data to this e-mail (I hope it's small enough that that's ok).
First I paste all the commands I ran, followed by the

round function seems to produce maximum 2 decimals
I am trying to use round()to force R to display a specific number of
decimals, but it seems to display <=2 decimals no matter what I specify in
the digits argument. As an alternative I tried signif(), but it also
produces unexpected results. See example code and results below. Format()
works, but then the result no longer is numeric. Am I missing something
simple?
I am using R 2.9.0 on Windows

Question on Round function
I happened to see these:
> round(.5, 0)
[1] 0
> round(1.5, 0)
[1] 2
> round(2.5, 0)
[1] 2
> round(3.5, 0)
[1] 4
> round(4.5, 0)
[1] 4
What is the rule here?
Should not round(.5, 0) = 1, round(2.5, 0) = 3 etc?
Thanks and regards,

round.Date and trunc.Date not working / implemented
Technically, there is a round() for 'Date' objects, but it doesn't
seem very useful, because it basically just fall back to the default
round() method, which only takes the 'digits' argument.
Here's an example:
> date <- Sys.Date()
> class(date)
[1] "Date"
We see that there are only two round() methods in addition to the
implicit built-in one;

round(1.5) = round(2.5) = 2?
Dear R-users
with a bit of grief I had to repeat an extensive analysis because I
did not suspect (and therefore did not read the documentation) that
round was implemented as "for rounding off a 5, the IEC 60559 standard
is expected to be used, 'go to the even digit'", resulting in
round(1.5) = 2
round (2.5) = 2.
As a non-mathematician I am both puzzled and intrigued by

round.Date and trunc.Date not working / implemented
This is a workaround, and could be the basis for a round.Date improvement:
date <- Sys.Date()
as.Date(round(as.POSIXct(date), "years"))
as.Date(round(as.POSIXct(Sys.Date() + 180), "years"))

That would work, perhaps structured similarly as `trunc.Date` is.
The only issue might be that `trunc.Date` is currently using

float calculation error
Hi
I have the following values
pActualCost = 33.00
pPaymentCost = 29.99
So this calculation should leave me with 0.01
pPaymentDifference = pActualCost - pPaymentCost
however when doing this in rails, it returns 0.00999999999999801
has anyone got any suggestions to whats going wrong and how I can
correct this
Thanks
Scott

- round() strange behaviour
Hi,
I am getting some strange results using round - it seems that it depends if the number before the decimal point is odd or even ....
For example:
> round(1.5)[1] 2> round(2.5)[1] 2
While i would expect that round(2.5) be 3 and not 2.
Do you have any explanation for that?
I really appreciate your input,
Monica

Problems with pf() with certain noncentral values/degrees of freedom combinations
Hello all.
It seems that the pf() function when used with noncentral parameters can
behave badly at times. I've included some examples below, but what is
happening is that with some combinations of df and ncp parameters,
regardless of how large the quantile gets, the same probability value is
returned. Upon first glance noncentral values greater than 200 may seem
large, but they are in

round to specific intervals
Dear R users/helpers,
I am wondering is there an existing function in which you can round
numbers to a set of values. I know you can use 5 * round(x/5) for
rounding to the nearest 5 or so, but what if the interval size is not
constant.
For example:
## Not run
test <- rnorm(100)
round(test, c(1, 5, 10, 20, 50))
so that the test is rounded to the closest value in the vector.
Thanks for the

I've managed to patch the source, and install gcc and the necessary other

I'm unable to "make" the Makefile. Did some STFW'ing and have found

Animated gif or something similar in R?
I'm have a (minor) problem and a question.
Problem: The following code creates 5 clusters of dots of different
colors. However, I need the second call outside the data.frame call to
get the colors to change for some reason. I assume there's an error in
the data.frame() call, but I don't know what.
