Dear R users,
Any idea of how to calculate an area of an overlap between two functions? The
only R build in function that I found is I Similarity Statistic for Quantifying
Niche Overlap and I am really not sure if this function is producing exactly
what I am interested in since I was plotting

Hi there dear R users,
By using the code below that plots two distributions and calculates a bootstrap
hypothesis test of equality, similarity of these two distributions was
calculated. What I'm interested now is to find out a size of the area where
both distributions are overlapping. I know
Hi there dear R users!
Anyone knows why does matchit function returns error whenever the hull option
is used (either hull.both, hull.control or hull.treat). Things work well
with all the rest of discard options.
This is the error msg.

Hi there,
I'm wondering what Zelig in the following situation (code below) actually does.
Is this considered as a so called regression adjustment after the propensity
score matching?

data(lalonde)
re78 represents the outcome variable

Hi there,
I guess this is an easy one, but still:
I would like to randomly sample 0s and 1s but in a way that I end up having for
example 70% of 1s and the rest of 0s and not 50:50 as this function
does: sample(c(0,1), 100, replace = TRUE)
Any recommendations?
Many thanks!
Ana
Thanks! That works well.
Best,
Ana

Let's say I have an original data set which is called A and data extracted from
this original data set, called B. Based on these A and B data set I would like
to get data set C which includes all the remaining data from the data set A
after we exclude data of the data set B.
Any idea how to do
- match.data(m.out.base)
An - nrow(A)
Bn - nrow(B)
Cn - An - Bn
C - ??

Hi there,
Does anyone know how to extract data from a function that prints out two or
more summaries? In the function below (the whole code is provided) we get 5
different tables of data. I would like to split each of these tables in a
separate file (while the function itself shouldn't be

Hi there,
Anyone has an idea how to put those two sets of code together so that I can get
a 3-dimensional picture that includes points instead of 2 separate pictures
which doesnt make that much sense at the end.
#Let's say that these are the data we would like to plot:
A-c(62,84,53)
Ha. You understood my question perfectly ok and thank you for your answer.
Haven't thought that this might be the case, and it is, indeed!

Being a beginner with R makes thinks a bit more complicated.
This is the code:
