Example data:

save(df2, file="df2.RData")
My trials
# trying to load
data(df2)
The data() function load from package libraries.
Warning message:
In data(df2) : data set 'df2' not found
data(df2.RData)
Warning message:
In data(df2.RData) : data set 'df2.RData' not found
data("df2.RData")
Warning message:

load(df2)
Error in load(df2) : bad 'file' argument
load(df2.RData)

Without quotes around df2.Rdata, R thinks you want a file whose name
can be found in a character vector of that name that is already in the
workspace.
try:
load(file="df2.RData")
