Good spot Bill,
and the error message comes from tabulate().

Subject: Re: [R] weird "vector size cannot be NA/NaN" problem
Werner,
Thanks for sending the data.
The problem does seem to lie with describe() in pkg:Hmisc.
Frank may want to know that it can be triggered by
f <- function(n)describe(c(1:n,1/0))
f(18) #ok
f(19) #triggers the error
Perhaps it's related to the "at least 20 unique values" condition
mentioned in ?describe.
The call to range() in describe.vector needs the finite=TRUE
argument, so it returns the range of only the finite elements
of the input.

Hi,
I have to follow up my own question since this problem is
getting quite disturbing and I fear that it also causes other
functions to malfunction without notice.
It occurs quite quite often when I manipulate the mentioned
data set. It definitely is caused by the column entries which
are Inf (caused by a value/0 operation) but I cannot
reproduce the error. When I do a describe(c(5,3,76,4/0)), for
example, the last value is Inf but the error is not thrown.
But I can save the vector and load it and the error still
occurs. Would someone be willing to look at that vector and
maybe finds out the root of the problem? (I'll send the
vector by email)
As I said in the earlier email, the data is imported with
read.dta of the foreign library and the only manipulation I
do is dividing the values of two columns by each other.
Thanks a million,
Werner
I have a weird problem with my data but I cannot really
locate it and cannot make a small example data set do
reproduce the problem.
I basically divide one numerical column of a data frame
with another. When I run describe() on that column, I get
"Error in vector("integer", length) : vector size cannot be
NA/NaN"
The two original columns comprise many zero values and I
think the particular row which causes the problem ends up
with an "Inf".
I fear that other functions might also not be reliable for
this data and that I have to repair it somehow. It actually
happens with many of the variables from the various tables
which originally are in Stata .dta format and which I import
with the foreign library.
I am working on windows XP and R 2.9.1
I assume that this description is too vague but if anybody
has an idea, I would appreciate it.
Thanks so much,
Werner
