I'd like to use a dashed hook right arrow instead of a classic one in my LaTeX document, but I don't know how to create one. MWE:

documentclass[a4paper]{article}

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

usepackage{fullpage}



usepackage{amsmath}

usepackage{amssymb}

usepackage{amsthm}

usepackage{mathtools}

usepackage{tikz-cd}



begin{document}

 [

 begin{tikzcd}[row sep=huge, column sep=large]

  Z arrow{r}{Phi} arrow[twoheadrightarrow]{d} & R \

  Z_n arrow[hookrightarrow]{ru}[swap]{bar{Phi}}

 end{tikzcd}

 ]

end{document}

Add the keyword dashed. There's a simpler syntax available, which doesn't require to remember the argument positions.

Note that hook is sufficient. Similarly, two heads is simpler than twoheadrightarrow.

documentclass[a4paper]{article}

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}



usepackage{amsmath}

usepackage{amssymb}

usepackage{amsthm}

usepackage{mathtools}

usepackage{tikz-cd}



newcommand{Z}{mathbb{Z}}



begin{document}



[

begin{tikzcd}[row sep=huge, column sep=large]

  Z arrow[r,"Phi"] arrow[d,two heads] & R \

  Z_n arrow[ru,hook,dashed,swap,"bar{Phi}"]

end{tikzcd}

]



end{document}
