I assume that you saved the data.tables using save()
somewhat like this:
d1 <- data.table(value=1:10)
save(d1, file="data1.rdata")
and your problem is that when you load the file you don't know the name (here: d1) that you used when saving the file. Correct?
I suggest you use instead saveRDS()
and readRDS()
for saving/loading single objects:
d1 <- data.table(value=1:10)
saveRDS(d1, file="data1.rds")
blob <- readRDS("data1.rds")
