For some reason that instance of Julia 0.3 *didn't* recognize eval or a
number of other functions. I was trying to use readtable from DataFrames
and it didn't recognize it despite having the latest version. After doing a
Pkg.update() only an unused package was updated so I restarted Julia.
Afterwards everything worked. If I am able to reproduce the error I will
try and submit a bug.
Your suggestion worked quite well. It's not something I had considered
before because I didn't think you could give it a string until I saw
IOBuffer used elsewhere recently.
cols = readcsv(IOBuffer(colsStr))
One problem I ran across while doing something similar is the type is
baffling me.
julia> y = [symbol("$i") for i in cols]
4-element Array{Any,1}:
:TIMESTAMP
:RECORD
:Volt_CR3000_Min
:LoggerTemp_CR3000
julia> y = [symbol("$i") for i in 1:5]
5-element Array{Symbol,1}:
symbol("1")
symbol("2")
symbol("3")
symbol("4")
symbol("5")
julia> y = [symbol("$i") for i in [1:5]]
5-element Array{Symbol,1}:
symbol("1")
symbol("2")
symbol("3")
symbol("4")
symbol("5")
Why is the first instance an Array{Any,1} where the second two are
Array{Symbol,1}?
