# R data.frame() Function - Create Data Frame
[ R Language Examples](#)
The R data.frame() function is used to create data frames, which is one of the most core data structures in R.
A data frame is similar to a table, where each column can be a different type of data (numeric, character, logical, etc.), but each column must have the same length.
The syntax format of the data.frame() function is as follows:
data.frame(..., stringsAsFactors = default.stringsAsFactors())
**Parameter Description:**
* **...** Column data, which can be vectors, lists, or matrices.
* **stringsAsFactors** Whether to automatically convert strings to factors (default is FALSE starting from R 4.0).
## Example
```R
# Create DataFrame
df<-data.frame(
ID =1:5,
Name =c("Zhang San", "Li Si", "Wang Wu", "Zhao Liu", "Qian Qi"),
Age =c(25, 30, 28, 35, 22),
Score =c(88, 92, 76, 85, 90),
stringsAsFactors = FALSE
)
print("DataFrame Content:")
print(df)
# View Basic Properties
print("Structure:")
print(str(df))
print(paste("Number of Rows:", nrow(df), "Number of Columns:", ncol(df)))
print("Column Names:")
print(colnames(df))
Executing the above code outputs the following result:
```text
"DataFrame Content:" ID Name Age Score1 1 Zhang San 25 882 2 Li Si 30 923 3 Wang Wu 28 764 4 Zhao Liu 35 855 5 Qian Qi 22 90 "Structure:"'data.frame':5 obs. of 4 variables: $ ID: int 1 2 3 4 5 $ Name: chr "Zhang San" "Li Si" "Wang Wu" "Zhao Liu" ... $ Age: num 25 30 28 35 22 $ Score: num 88 92 76 85 90 "Number of Rows: 5 Number of Columns: 4" "Column Names:" "ID" "Name" "Age" "Score"
