Sukhdeep has the right answer, data() is really for getting datasets from packages or the standard library in R. Just so you know, if you do create a package then plain text tables are one of of the formats that you can use in the /data directory (as per the documentation) - i.e. there is no reason to save your data in the binary format

You read a table in a variable named values

values<- read.table("mydatasetname.txt")

you saved a image as an .rda (Rdata) file

save(values,file="value.rda")

To load it , use the load command as load('value.rda')

This will load the image you saved capturing the table you read. To confirm, type ls() which will list the values variable and typing it will output the values stored in it. Also, the data command is to load the data provided by default with the packages, so if you write data(), it will give you a list existing datasets.

Cheers
