Constructer of the bstr class object

bstr(x, n, ucase = FALSE)

dstr(x, n, ucase = FALSE)

astr(x, n, ucase = F)

is_bstr(x)

is_dstr(x)

is_astr(x)

as_bstr(x, n, ucase = FALSE)

as_dstr(x, n, ucase = FALSE)

as_astr(x, n, ucase = FALSE)

Arguments

x	A character vector which convert to a bstr object.
n	A character vector which is name of x.
ucase	A logical. If TRUE the x is converted to upper case. (default: FALSE)

Examples

bstr("Apple", "apple")
#> class: bstr,character 
#> number of sequences: 1 
#> [1]        apple        : Apple                                    5 
bstr(c("Apple", "potato"), c("apple", "imo"), ucase = TRUE)
#> class: bstr,character 
#> number of sequences: 2 
#> [1]        apple        : APPLE                                    5 
#> [2]         imo         : POTATO                                   6 

dstr("A.Bad.bat", "It is")
#> class: dstr,bstr,character 
#> number of sequences: 1 
#> [1]        It is        : A.Bad.bat                                9 
dstr(c("A", "bad", "Bat"), ucase = TRUE)
#> class: dstr,bstr,character 
#> number of sequences: 3 
#> [1]      no name 1      : A                                        1 
#> [2]      no name 2      : BAD                                      3 
#> [3]      no name 3      : BAT                                      3 

astr("Wqrld", "HELLQ", ucase = TRUE)
#> class: astr,bstr,character 
#> number of sequences: 1 
#> [1]        HELLQ        : WQRLD                                    5 

### Check class
is_bstr(bstr("apple"))
#> [1] TRUE
is_bstr(c("apple", "orange"))
#> [1] FALSE
is_dstr(dstr("bad"))
#> [1] TRUE
is_astr(astr("I.am.a.geek"))
#> [1] TRUE

### Convert character to bstr object
as_dstr("bad", "good", ucase = TRUE)
#> class: dstr,bstr,character 
#> number of sequences: 1 
#> [1]         good        : BAD                                      3 
# as_dstr(c("good", "bad")) # Error
as_astr("Wqrld", "HELLQ", ucase = TRUE)
#> class: astr,bstr,character 
#> number of sequences: 1 
#> [1]        HELLQ        : WQRLD                                    5
