In-string variable/symbol substitution: What formats/syntax is out there?
Hi,
I'm try to collect a list of methods/packages available in R for doing
in-string variable/symbol substitution, e.g. someFcn("pi=${pi}"),
anotherFcn("pi=@pi@") and so on becomes "pi=3.141593". I am aware of
the following:
** gsubfn() in the 'gsubfn' package, e.g.
> gsubfn( , , "pi = $pi, 2pi = `2*pi`")
[1] "pi = 3.14159265358979, 2pi = 6.28318530717959"

window function
Dear Sebastian and all,
This is a Japanese to live in Japan.
I have a question.
Ogg's window functon is
f(x)=sin(1/2*pi*sin^2((x+0.5)/n*pi)) for 0 <= x < n
But I cannot understand why this window function satisfys
the equation
f^2(x)+f^2(x+n/2)=2
which is for MDCT's perfect signal reconstruction.

Problem in applying conditional looping
Respected All,
I hope you are enjoying good health, I am tring to write a program in R but
could not be very sucessful. My program draws random sample form bivariate
normal distribution and then compute a variable PIJ. For certian samples
some entries of variable PIJ is apearing as negative, which result
in negative variance estimator. I want to introduce a loop in my program
that verify the each value of PIJ and if any value in PIJ is negitive return
back and draw another sample until a sample is selected that...

plot numerous functions in one figure with different values of x per function

I am not a professional programmer so please excuse me if my questions seem
naive.
I have only begun using R to solve some problems and I'm already regretting
it
1.
I am trying to plot different functions in the same figure. The first
function
f(x)= sin(x)+(pi/4) , -2pi<=x<=2pi
the second function
g(x) = {sin(x), 0 <= x <= pi or ?2pi <= x <= -pi

my code is:

> fx<- (sin(x)+(pi/4))

write() gotcha
Hi
I used write() the other day to save some results.
It seems that write() does not record the full precision of
the objects being written:
> write(pi,file="~/f",ncolumns=1)
> pi.saved <- scan("~/f")
Read 1 item
> dput(pi)
3.14159265358979
> dput(pi.saved)
3.141593
> pi-pi.saved
[1] -3.464102e-07

This difficulty was particularly difficult to find because pi.saved
*looks*
the same as pi.

Value of 'pi'
Dear R helpers,
I have one basic doubt about the value of pi. In school, we have learned that
pi = 22/7 (which is = 3.142857). However, if I type pi in R, I get pi = 3.141593. So which value of pi should be considered?

[PATCH] nr_cpus calculation problem due to incorrect sockets_per_node
...9;s nr_cpus calculation. In this case, since Xen cuts off recognized
CPUs at 32, the machine appears to have 16 CPUs on the first and second
nodes and none on the remaining nodes. Given this asymmetry, the
calculation of sockets_per_node (which is later used to calculate
nr_cpus) is incorrect:
pi->sockets_per_node = num_online_cpus() /(num_online_nodes() *
pi->cores_per_socket * pi->threads_per_core);
The most straightforward solution is to remove sockets_per_node, and
instead determine nr_cpus directly from num_online_cpus.
This patch has been tested on x86_64 NUMA machines....
