profiler and loops
...3.html but
with a different focus)
I am often confused by the result of the profiler, when a loop is
involved. Consider these two scripts:
script1:
Rprof( )
x <- numeric( )
for( i in 1:10000){
x <- c( x, rnorm(10) )
}
Rprof( NULL )
print( summaryRprof( ) )
script2:
Rprof( )
ffor <- function(){
x <- numeric( )
for( i in 1:10000){
x <- c( x, rnorm(10) )
}
}
ffor()
Rprof( NULL )
print( summaryRprof( ) )
[]$ time Rscript --vanilla script1.R
$by.self
self.time self.pct total.time total.pct
"rnorm" 0.22 100 0.22 100...

Export Results to a txt file applying a function to a list
...*****\nDataset Sim : ",
i )
d<-data%*%t(data)
s<-solve(d)
print(s)
out<-s
out
}
######First using for I take my results (for some element of a list I can't
have results due to invertibility or convergence problem helpful suggestion
of Joris Meys )
results<-list()
ffor(i in 1:5){
tmp <- try(fun(data=S[[i]]))
results[[i]] <- ifelse(is(tmp,"try-error"),NA,tmp)
}
#####and so I can see using "cat" the results for each dataset.
#####I want to use lapply at the last step istead of for to make faster my
program
results <- lapply...

problem with user defined panel function in xyplot
...graph as i want it. Now i want to use this graph as
a panel function in xyplot function from lattice to get the nice lattice type
of graph for all my categories in my time series. And ?.. i am getting this
error:" Error using packet 1, Argument "ts01" is missing with no
default"fFor each of my columns.
?
Now my function called panel.tsfold takes as argument one
column from a time series or a zoo object that has only 1 time series. How can
i make the xyplot function to send to the panel function one column from the
bigger time series dataset?
?
My command that gives me erro...

Hello,
I''m going to be helping a friend setup Shorewall in place of his Cisco
router on his home network. Shorewall will be acting as the router/firewall
gateway for internet access for his home LAN. His connection to the ISP is
via PPPOE. Nothing unfamiliar here to me. It will be a standard 2 interface
setup.
My curiosity was peaked when he said that he is going to be installing
