r.args

Furthermore, r.args function returns all the arguments of a function in the next line of code

Select text string of a function in the R Script and run:

# r.args()
# 
# rnorm(n=32)
# n=32;mean=0;sd=1
# 
# rnorm(n=32.3)
# n=32.3;mean=0;sd=1
# 
# rnorm(n=1+1)
# n=1+1;mean=0;sd=1
#

libraries

Finally, libraries() function run all libraries written in a R Script (and installs the package if it does not exist)

# libraries()
