kernel density estimates
Dear All,
I have a variable q which is a vector of 1000 simulated positive values; that is I generated 1000 samples from the pareto distribution, from each sample I calculated the value of q ( a certain fn in the sample observations), and thus I was left with 1000 values of q and I don't know the distribution of q.
Hence, I used the given code for kernel density estimation to estimate the

Strange behavior when using progress bar (Fwd: Re: [R] The code itself disappears after starting to execute the for loop)
I first answered to the email below in r-help, but as I did not see any
response, and it looks like a bug/unwanted behavior, I am also posting
here. I have observed this in RGui, whereas it seems not to happen in
RStudio.
Similar to OP, I sometimes have a problem with functions using the
progress bar. Frequently, the console is cleared after x iterations when
the progress bar is called in a

The code itself disappears after starting to execute the for loop
Hi all,
I've a question concerning the R 3.3.1 version. I have a long code that I used to run on versions earlier to the 3.3.1 version, and when I copied the code to the R console, I can still see the code while the loop is executing , along with the output printed after each iteration of the loop.
Now, on the 3.3.1 version, after I copy the code to the console, it disappears and I only see

axis label
Hi all,
I want the y-axis label to be ( in symbols)
g(sigma given alpha)
where given is the conditional sign.
I've tried
ylab=expression(g(sigma|alpha)))
but it gave me
g(|(sigma,alpha))
where the sigma and alpha are in greek but the conditional sign is misplaced (before the bracket)
Any help would be appreciated.

solving a linear equation
Hi all,
I've a linear equation of the form:
0.95=2 ( [3+ln(x/3)]^-13 + 4 [3+2ln(x/3)]^-13 + [3+4ln(x/3)]^-13 )
and I want to solve it for x, can I do this using R?
Thanks in advance.

How can I use the histogram density estimate (hist) to find the value of the cdf at a certain point?

Hi Group,
I've a vector of 1000 numeric values for which I want to draw a histogram. I've read this vector into R with no variable name.I mean only the 1000 values, which makes V1 the name of the variable by default?? Then I tried

I would like to ask once more if this is reproducible also for others?
If yes, should I submit it as a bug-report?
Best,

finding the minimum value
Hi all,
I'm using a certain procedure to calculate the value of some variable(Bayes risk),B.
So I got the values B1, B2, ........, B1000, each under certain input values and using a long procedure.
Now, I want to put the values I got in a nummerical vector and find their minimum value. I think c( ) should work.For example if I have only 10 values I could have used

cdf
Dear all,
I have the cdf of the following power fuction distribution:
F(y)=(y/350)^a ,0<y<350,
where " a " is some parameter with range a>0.
I want to use it as the argument of the discretize function of the actuar package.
So I think I need to define this function to R so that if I entered a=1, I get the following
F(y)=(y/350)
and if I entered a=4.5, I get the

calculating probability
Hi all,
I've a trivial question. If (q) is a continous variable,actually a vector of 1000 values. how to calculate the probability that q is greater than a specific value, i.e. P(q>45)??
Thanks

Fw: solving a linear equation
Sorry, I didn't mean a linear equation, of course this equation is not linear, I meant an equation in one unknown.
Hi all,
I've a linear equation of the form:

Dear group,
Thank u so much 4 ur help. I've tried the link,
http://finzi.psych.upenn.edu/R/library/quantreg/html/akj.html
for adaptive kernel density estimation.
But since I'm an R beginer and the topic of adaptive estimation is new for me, i still can't figure out some of the arguments of
akj(x, z =, p =, h = -1, alpha = 0.5, kappa = 0.9, iker1 = 0)
