[R] not sure if this intended behavior in column referencing

2006-11-14 Thread Leeds, Mark \(IED\)
I made smaller zoo object with one column with the structure below

smooththirtylogbidask<-structure(c(4.77126598671015, 4.77127449545028,
4.77128569715842, 
4.77129917), index = structure(c(1144022520, 1144022580, 
1144022640, 1144022700), class = c("POSIXt", "POSIXct")), class = "zoo")

And then I printed it out 3 different ways as below.

print(smooththirtylogbidask[,])
print(smooththirtylogbidask[,"logbidask"])
print(smooththirtylogbidask[,"xxx"])

All of them worked in that they printed out the EXACT same correct thing
which tells me that the column reference you
put in is ignored when the object is just one column. I am unsure if
this intended 
general R behavior, intended general zoo behavior or just unintended
behavior but I figured I would send this info out.

Please make your examples minimal.  That includes not using
huge variable names that make it harder to work with.

This is not a zoo object with one column.  Its is a zoo object
based on a vector.

zoo(matrix(1:3, 3, 1))

is not the same as

zoo(1:3)

The former has one column but the latter does not have two dimensions
therefore the idea of columns is meaningless.
