find closest value in a vector based on another vector values
...tract from "a" the two values that are closest to the values in "b", where the length of this vectors may change but b will allways be shorter than "a". So at the end based on this example I should have the result "f" as
f <-c(8,32)
appreciate the help,

Vary an equation using values from a sequence
...such, but this seems like overkill. I am wondering if there is a simple solution that would allow me to accomplish this.
The code I am using is outlined below.
Data <- c(1:10) #Data
value <- seq(from = 0, to = 100 , by = 0.01) #Sequence
Data - min(Data) + k # Equation
Thanks,

Help on numerical object and ifelse function
...andle on it:
x <-c(1,2,3,4,5)
y <-c(6,7,8,9,10)
z <-15
w <-ifelse(z>14,x,y)
this will give me a value of 1 for w. What I would like to get is the whole string of x, so that w would become a numeric object of 5 characters exactly the same as x.
Apreciate the help,
Sincerely,

GLM question

glm.fit = flm(y~final_str,family=binomial())
but final_str is treated as a string and it does not work. Could you please help me with fixing that?

Any ideas of why that may be happening?

Hieraki + FCGI + Problem
...I try to run dispatch.fcgi from the command line, I got no fatal
error, it just says, that has routing problems.
Any ideas, what should I check? I''m not familiar with the FastCGI

application, or not, etc.
Bye,
Andras
ps: I''ve tried some other Rails applications, too, and - except Typo -
it''s the same problem with FCGI.
