This is simple tutorial for saving and loading data to R. For example I assign the data to variable x
x <- 1:50
Show x
x
## [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
## [24] 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46
## [47] 47 48 49 50
And then save to /Users/macintosh/Rdata/
save(x, file="/Users/macintosh/Rdata/x.Rdata")
After we save the data, now I delete variable x
rm(x)
show x
x
## Error: object 'x' not found
Now we don't have variable x , so we load x from the x.Rdata
load("/Users/macintosh/Rdata/x.Rdata")
And the last one, show variable x, with command x or print(x)
x
