Hi the list
Is it possible to give two names for a class ? One long name for using
in programmation, and one short name for the quick and durty uses ?
With function, we can do
mcf - myCoolFunction - function(x)
With class, I define clusterizedLongData, I want to use it with the
full name
Gabor,
Many thanks for your suggestion. This solution is very close, but not exactly
what I had in mind, because na.omit removes the entire row in which an NA
appears. I want to replace values in old with non-NA values from corresponding
times in new. If a timestamp from old does not appear

That creates a new function
Hi
Consider the following code
x - rep(1:13, 13)
y - 1:3
I want to select all elements in x which are equal to 1, 2 or 3.
I know that I could use
sel - x==y[1] | x==y[2] | x==y[3]
x[sel]
to obtain the values, but in my analysis, the y-vector is thousands of
elements long.
Is there any
Not easily.
Ok
So you could probably write a function that tracked down and copied
all the pieces, but it's not easy.
b. Well, you're right, it's not worth it.
So I will define a class ClusterizLongData then a constructor
cld - clusterizLongData - function(){new(ClusterizLongData)}
