: [R] lapply - value changes as parameters to function?
Thanks Jim. That did the trick.
I had wondered in passing about that as all the examples in the
?lapply page were pretty simple and each time it was the first
argument. However I didn't read that this was a requirement so I
didn't go ther

Change the order of the parameters in your function so that Lookback
is the first one. The first parameter of the lapply is what is passed
to the function as its first parameter. Now just have
ResultList <- lapply(x, DoAvgCalcs, IndexData=IndexData,
SampleSize=TestSamples, Iteration=TestIteratio
Phil,
Thanks for the reply. Your suggestion is actually the one I started
with (assuming I'm understanding you) but I didn't seem to even get
down into my function, or the error message is from other place within
my function that I haven't discovered yet:
> x = seq(5:20)
> ResultList = lapply(x
Mark -
The "l" in lapply refers to that fact that it will *return*
a list, not that it wants a list for input. You could input
a list, but then each element of the list would be one of the
values you wanted processed. So I think you want
x = seq(5:20)
ResultList = lapply(x, DoAvgCalcs, In
Hi,
I'm trying to get better at things like lapply but it still stumps
me. I have a function I've written, tested and debugged using
individual calls to the function, ala:
ResultList5 = DoAvgCalcs(IndexData, Lookback=5,
SampleSize=TestSamples , Iterations=TestIterations )
ResultList8 = DoAvgC
7 matches
