Usage of practicals via BristolVis

The practical exercises and their solutions can be displayed via the BristolVis package using:

vignette("prac_IntroR", package = "BristolVis")
vignette("prac_base", package = "BristolVis")
vignette("prac_advanced", package = "BristolVis")
vignette("prac_AdvMore", package = "BristolVis")
vignette("prac_interactive", package = "BristolVis")
vignette("prac_RMarkdown", package = "BristolVis")
vignette("prac1_shiny", package = "BristolVis")
vignette("prac2_shiny", package = "BristolVis")
vignette("prac3_shiny", package = "BristolVis")
vignette("prac4_shiny", package = "BristolVis")

Solutions of some of these practical exercises can be displayed via the BristolVis package as follows:

vignette("ans_IntroR", package = "BristolVis")
vignette("ans_base", package = "BristolVis")
vignette("ans_advanced", package = "BristolVis")
vignette("ans_AdvMore", package = "BristolVis")
vignette("ans_interactive", package = "BristolVis")
