Error; object of type 'closure' is not subsettable

Hi Guys

I have quick question if you have a spare minute.

I am using the function below named 'functionx'

function (data = data1, n0 = 1000, m = 5000)
{
xnamesls = makesubsets(data, maxsize = dim(data)[2])
M = length(xnamesls)
thetamls = mapply("factort", xnames = xnamesls, MoreArgs = list(data = data,
nu = nu, trainpct = trainpct, priorczz = priorczz, diag = diag,
n0 = n0, m = m), SIMPLIFY = FALSE)
outls = vector("list", M)
modnames = rep(0, M)
for (i in 1:M) {
logmargi = attr(thetamlsi, "logmarg")
outls[[i]] = list(xnames = xnamesls[[i]], logmarg = logmargi)
}
names(outls) = modnames
scandf = makedffrommscan(scanls = outls, data = data)
scandford = scandf[order(scandf$logmarg, decreasing = T),
]
scanls = list(scandf = scandf, scandford = scandford, scanls = outls)
return(scanls = scanls)
}

The object of interest is the highlighted 'scandf'.

However when I try to extract this function of interest using the below command:

scandf = functionx$scandf

I get the error ;

object of type 'closure' is not subsettable.

I see online this means I am treating the function like a data frame, but I am unsure how to correct this issue.

Do you guys know how to access an item within a function using $, or is there a better way for me to do this?

Thanks in advance

Alan

Is you want scandf then make the function return that object instead of scanls and then you can do

scandf <- functionx()

Any function in namespace—df and data, among many more—can do this, but not always. It's best to avoid using these "reserved words" or to mimic them with capitalization or adding a suffix, such as df_.
