I need to convert a dataframe to a record-structure, to be able to encode it
later in JSON. Suppose this is the data:
mydata <- data.frame(foo=1:3, bar=c("M","M","F"));
I would like to convert this to a unnamed list (json array) of key-value
pairs. For example like this:
apply(data.frame(foo=1:3, bar=c("M","M","F")),1,as.list)
However, when I do this, all the numeric values are converted to strings. I
don't understand why this is, because when I try to convert one record
simulataniously, this does not happen:
as.list(mydata[1,]);
I am not sure if this is indended behaviour or not, but is there an elegant
way to apply 'as.list' to all of the dataframe rows without coercing
everything to strings?
