Пример кода для хранения всех данных в data.frame s:
library("RSQLite")
## connect to db
con <- dbConnect(drv=RSQLite::SQLite(), dbname="YOURSQLITEFILE")
## list all tables
tables <- dbListTables(con)
## exclude sqlite_sequence (contains table information)
tables <- tables[tables != "sqlite_sequence"]
lDataFrames <- vector("list", length=length(tables))
## create a data.frame for each table
for (i in seq(along=tables)) {
lDataFrames[[i]] <- dbGetQuery(conn=con, statement=paste("SELECT * FROM '", tables[[i]], "'", sep=""))
}
