When I call matrices from a function, they are called but are not
recognized as matrices. I use the code below. From the main function, when
I use the command is.matrix(), the response is FALSE. Why are the matrices
not recognized as matrices? Thanks in advance for any guidance.
#This function creates matrices and returns them in a list.
my_func <- function() {
matrix_1 = matrix(c(1,2,3,4), ncol = 2, nrow = 2)
matrix_2 = matrix(c(5,6,7,8), ncol = 2, nrow = 2)
my_list <- list(matrix_1,matrix_2)
return(my_list)
}
#This function calls the myfunc function.
main_func <- function() {
result <- myfunc()
result_1 <- (result[1])
print(result_1)
print(is.matrix(a))
result_2 <- (result[2])
print(result_2)
print(is.matrix(result_2))
}
main_func()
> #This function creates matrices and returns them in a list.
> my_func <- function() {
+ matrix_1 = matrix(c(1,2,3,4), ncol = 2, nrow = 2)
+ matrix_2 = matrix(c(5,6,7,8), ncol = 2, nrow = 2)
+ my_list <- list(matrix_1,matrix_2)
+ return(my_list)
+ }
> #This function calls the myfunc function.
> main_func <- function() {
+ result <- myfunc()
+ result_1 <- (result[1])
+ print(result_1)
+ print(is.matrix(a))
+ result_2 <- (result[2])
+ print(result_2)
+ print(is.matrix(result_2))
+ }
