Integration in R
Dear R-users,
I am facing problem with integrating in R a likelihood function which is a
function of four parameters. It's giving me the result at the end but
taking more than half an hour to run. I'm wondering is there any other
efficient way deal with. The following is my code. I am ready to provide
any other description of my function if you need to move forward.

scanning data in R
Dear R-user,
May I seek your suggestion. I have a data file 'stop' to be scanned in R.
But I want to ignore one specific number '21' there. Putting differently, I
want to get all numbers in the file except 21. Is there any command to
achieve it?

b<-scan("F:\\stop.txt")

Minimizing Computational Time
Dear R-users,
May I seek some suggestions from you. I have a long programme written in R
with several 'for' loops inside. I just want to get them out by any elegant
way (if there is!) to reduce the computational time of the main programme.
For instance, is there any smart way for the following programme that will
lessen time?

vertical lines in R plot
Dear All,
May I seek your suggestion on a simple issue. I want to draw vertical lines
at some positions in the following R plot. To be more specific, I wish to
draw vertical lines at d=c(5.0,5.5,6) and they should go till
p=c(0.12,0.60,0.20) . I haven't found any way out, though made several
attempts. Please run the following commands first if you are interested in!

Percentages in bar plot
Dear R-users,
Though it's a silly thing to ask, but I'm not getting a way out. I wish to
find the percentage distribution for a data vector 'stop'. The coomand
below is giving the frequency distribution. May I know the option to see
the percentages instead of frequencies. Similarly, what option I should
put in a histogram plot to see the percentages instead of frequencies?

Integration in R
Hi R-users.
I'm having difficulty with an integration in R via
the package "cubature". I'm putting it with a simple example here. I wish
to integrate a function like:
f(x1,x2)=2/3*(x1+x2) in the interval 0<x1<x2<7. To be sure I tried it
by hand and got 114.33, but the following R code is giving me 102.6667.

PFIM 3.2
Dear R-user,
I'm having some difficulty with working PFIM 3.2, a package for
implementing population PK/PD in R. I wish to evaluate the determinant of
Fisher information matrix each time with successive dose from a pre defined
sequence of doses and want to store those values in a vector. It's
important to note that in my 'stdin.r' file, dose<-c(u) and each time u is
to be
