Execute expression ( R -e) without close
I need to find a way how to execute an expression with the new command line
parameter in R (R -e "AnExpression") without R get closed after the
expression has been evaluated.
For example if i want to start R with a plot or start R with a *.RData file.
Any help or suggestions are appreciated !

matlab norm(h) command in R: sqrt(sum(h^2)) - use in an expression
Hi
in matlab I defined a function (double gamma, parameters at the end of
this mail) as
h(i)=((t/d1)^a1)*exp(-(t-d1)/b1)-c*((t/d2)^a2)*exp(-(t-d2)/b2);
h=h/norm(h);
I do know that norm() in matlab is equal to:
sqrt(sum(x^2))
in R
so in R I do it like:
#function (double gamama)
h <- expression((t/d1)^a1*exp(-(t-d1)/b1)-c*(t/d2)^a2*exp(-(t-d2)/b2))
# plot it
t <- seq(0, 20000,
