How to define string arrays in R language?

In R language, you can use a character vector to define a string array. One way to define a string array is by using the c() function to place multiple strings together. For example:

str_arr <- c("字符串1", "字符串2", "字符串3")

2. Assigning character vectors: You can assign multiple strings to a character vector to define a string array. For example:

str_vec <- c("字符串1", "字符串2", "字符串3")
str_arr <- str_vec

3. Using character vector indexing: Access and modify elements of a character vector through indexing, thus defining a string array. For example:

str_vec <- character(3)
str_vec[1] <- "字符串1"
str_vec[2] <- "字符串2"
str_vec[3] <- "字符串3"
str_arr <- str_vec

No matter how you define a string array, you can access and modify elements in the array by index. For example, using `str_arr[1]` can access the first element in the string array.
