lists and vectors

Examples

print_list(list())
#> <empty>
#> 
print_list(c())
#> <empty>
#> 

testvec <- seq(3)
names(testvec) <- LETTERS[seq(3)]
print_list(testvec)
#> A : 1
#> B : 2
#> C : 3

test <- list(
    name1 = "1",
    longername2 = "test_char",
    thirdname = factor("this will be converted with as.character()"),
    df_test = data.frame(a = "a", b = "b"),
    list_test = list(a = 1, b = 2, c = 3),
    formula_test = ~a
)
print_list(test)
#> name1        : 1
#> longername2  : test_char
#> thirdname    : this will be converted with as.character()
#> df_test      : <data.frame> length 2
#> list_test    : <list> length 3
#> formula_test : <formula> length 2
print_list(test, pre = "* ")
#> * name1        : 1
#> * longername2  : test_char
#> * thirdname    : this will be converted with as.character()
#> * df_test      : <data.frame> length 2
#> * list_test    : <list> length 3
