How to use saveRDS and readRDS method In R Language

Method 1: Using save.image and load method

Method 3: Using the save and load method

The saveRDS and readRDS methods available in base R are basically used to provide a means to save a single R object to a connection, mostly a type of file object, and then to restore the object. The restored object may belong to a different name. This approach is different from the save and load approach, which saves and restores one or more named objects into an environment. It is used to save a single object into the workspace.

Syntax:

saveRDS(object, file = “”)

Arguments :

object – R object to serialize.

file – name of the file where the R object is saved to or read from.

Syntax:

readRDS(file)

Example: Saving and loading R data workspace

R

# creating data objects
obj1 <- c(1:5)          
obj2 <- FALSE                      
obj3 <- "w3wiki!!"  
 
# saving all data to the path
saveRDS(obj1, file = "saveworkspaceobj1.RData")
print("Data object1")
 
# loading the workspace
readRDS("saveworkspaceobj1.RData")
