Well, your question looks quite interesting to me.
*which *function normally returns a non-negative *integer *and if fails
to find the case, then returns integer(0) that is an integer with the zero
length. Logically it returns the right answer. Then, doing an operation on
nothing is pointless, how

Hi All,
I recently discovered an interesting issue with the punif() function. Let
X~Uiform[a,b] then the CDF is defined by F(x)=(x-a)/(b-a) for (a<= x<= b).
The important fact here is the domain of the random variable X. Having said
that, R returns CDF for any value in the real domain.

Dear R Help Team.
I get some weird results when I use the lm function with weight. The issue
can be reproduced by the example below:
The input data is (weights are intentionally designed to reflect some
structures in the data)
> df
y x weight
1.51156139 0.55209240 2.117337e-34
-0.63653132 -0

am recently updated to R 3.5.0 and noticed some weird errors in write()
function. Further, I noticed that write.csv, write.table and generally the
functions that derive from write() are all weird.
1. write() function does not accept a path longer than 256 characters
