[R] re ad and check table
Dear R users, I want to read a file like following : if it is a table then z - read.table(pathname, dec=., header=TRUE) else if it's not a table (image,doc,...) then send an error or something like that acually I have a read.table in the beginnig of my R code, and if my data is not a table I become in my R console : fail in scan. So the question is how to check the nature of the file? something like : is.table? I don't know the function.

Re: [R] eval.wih.vis
I solved my problem.
I had to delete stop()
It doesn't make sense to have a stop() in if. stop() is to stop the
execution of the code once the condition is met.
the else does the job of stop() in this case.

[R] create a zero matrix fill
Dear R user,
I have written a function which returns max,min and variation of a power
(see below)
Power is a given matrix(1,n)
I call the function
Variation-VAR(p,(n-deltat))
Now the problem is when I want plot(Results[1],Results[2]). Not possible!
I become the following error (in english it means: Error in
as.double.default(x) :Object cannot be transformed in double)
plot(Variation[1],Variation[2])
Fehler in as.double.default(x) : (list) Objekt kann nicht nach 'double'
umgewandelt werden
Any suggestion?
Hier is the function:
#Computing variation of the power
VAR-function(power,length){
tvar=pmean=pmin=pmax=varmax=varmin-matrix(data=0,ncol=(length-tml0))
for(i in tml0:length){
tvar[i]=i
pmean[i]=mean(power[i:(i+deltat)])
pmin[i]=min(power[i:(i+deltat)])
pmax[i]=max(power[i:(i+deltat)])
varmax[i]=100*(pmax[i]-pmean[i])/pmean[i]
varmin[i]=100*(pmean[i]-pmin[i])/pmean[i]
Results=list(tvar,pmean,pmin,pmax,varmax,varmin)
}}
Thanks,
Adel

It looks like the best solution which could be done.

An easy way would be to have your condition results, which are
presumably TRUE/FALSE, in a vector such as:
Cond - c(TRUE, FALSE, FALSE, TRUE)
Then you could use all() to check to see if they are 'all' TRUE:
all(Cond)
[1] FALSE
Then use which() to get the index of the FALSE elements:
which(!Cond)
[1] 2 3
If you have your test labels in a character vector, such as:
Cond.Vec - c(Cond 1, Cond 2, Cond 3, Cond 4)
You could then use:
if (all(Cond)) {
Out - PASS
} else {
Out - paste(FAIL:, paste(Cond.Vec[which(!Cond)],
collapse = ))
}
Out
[1] FAIL: Cond 2 Cond 3
See ?all and ?which
