[ R Language Examples](https://example.com/r/r-examples.html)
The R str() function is used to quickly view the internal structure of R objects.
str() is a powerful tool for exploring data structures, it can display the object type, number of elements, and content preview.
The str() function syntax is as follows:
str(object)
**Parameter Description:**
* **object** The R object to view.
## Examples
# View vector structure
x <-c(1, 2, 3, 4, 5)
print("Vector structure:")
str(x)
# View data frame structure
df<-data.frame(
Name =c("Zhang San", "Li Si", "Wang Wu"),
Age =c(25, 30, 28),
Score =c(88.5, 92.0, 76.5),
stringsAsFactors = FALSE
)
print("Data frame structure:")
str(df)
# View list structure
my_list <-list(
name ="Zhang San",
age =25,
scores =c(88, 92, 76)
)
print("List structure:")
str(my_list)
Executing the above code produces the following output:
"Vector structure:" num [1:5] 1 2 3 4 5 "Data frame structure:"'data.frame':3 obs. of 3 variables: $ Name: chr "Zhang San" "Li Si" "Wang Wu" $ Age: num 25 30 28 $ Score: num 88.5 92 76.5 "List structure:"List of 3 $ name : chr "Zhang San" $ age : num 25 $ scores: num [1:3] 88 92 76
