Storing R Objects in a relational database

Question

I frequently create nonparametric statistics (loess, kernel densities, etc) on data I pull out of a relational database. To make data management easier I would like to store

Answer 1

Using textConnection / saveRDS / loadRDS is perhaps the most versatile and high level:

zz<-textConnection('tempConnection', 'wb')
saveRDS(myData, zz, ascii = T)
TEXT<-paste(textConnectionValue(zz), collapse='\n')

#write TEXT into SQL
...
closeAllConnections()  #if the connection persists, new data will be appended

#reading back:
#1. pull from SQL into queryResult
...
#2. recover the object
recoveredData <- readRDS(textConnection(queryResult$TEXT))
