gridpattern
v1.2.2
gridpattern 、RのGridグラフィックシステムで使用するgrid.pattern（）およびpatterngrob（）関数を提供します。ユーザー指定の境界パスをユーザー指定パターンで埋めます。これらのパターングローブには、元々Mike FCのAwesome Ggpatternパッケージに含まれていたパターンの拡張バージョンと、オリジナルの「PCH」、「Polygon_Tiling」、「Regulal_Polygon」、「Rose」、「Text」、「Wave」、「織り」パターンが含まれています。 。
{gridpattern}現在、次のパターンに{grid} grobサポートを提供しています。
開発バージョンをインストールするには、次のコマンドをRで使用します。

ggpattern 、 ggpattern v0.2.0以降、 gridpatternが提供するすべてのパターンを自動的にサポートします。 「ストライプ」パターンを使用する例は次のとおりです。
library( " ggpattern " ) # remotes::install_github("trevorld/ggpattern")
library( " ggplot2 " , warn.conflicts = FALSE )
library( " gridpattern " )
df <- data.frame ( trt = c( " a " , " b " , " c " ), outcome = c( 2.3 , 1.9 , 3.2 ))
ggplot( df , aes( trt , outcome )) +
geom_col_pattern(aes( fill = trt ), colour = ' black ' ,
pattern = ' stripe ' ,
pattern_fill = list (c( " grey30 " , " grey70 " , " white " , " grey70 " )))
ggpatternで使用するカスタムパターンを作成することもできます。以下は、 fill色、 pattern_fill色、および「平均」色を使用して、3色のポリゴンタイルを作成する「tiling3」パターンを作成する例です。
tiling3_pattern <- function ( params , boundary_df , aspect_ratio , legend = FALSE ) {
args <- as.list( params )
args <- args [grep( " ^pattern_ " , names( args ))]
# hexagonal tiling using "regular_polygon" pattern
args $ pattern <- " polygon_tiling "
# three-color tiling using `fill`, `pattern_fill` and their "average"
avg_col <- gridpattern :: mean_col( params $ fill , params $ pattern_fill )
args $ pattern_fill <- c( params $ fill , avg_col , args $ pattern_fill )
args $ x <- boundary_df $ x
args $ y <- boundary_df $ y
args $ id <- boundary_df $ id
args $ prefix <- " "
do.call( gridpattern :: patternGrob , args )
}
options( ggpattern_geometry_funcs = list ( tiling3 = tiling3_pattern ))
df <- data.frame ( trt = c( " a " , " b " , " c " ), outcome = c( 2.3 , 1.9 , 3.2 ))
ggplot( df , aes( trt , outcome )) +
geom_col_pattern(aes( fill = trt , pattern_type = trt ),
pattern = ' tiling3 ' , pattern_angle = 45 ) +
scale_pattern_type_manual( values = c( " hexagonal " , " tetrakis_square " , " rhombille " )) +
theme( legend.key.size = unit( 1.5 , ' cm ' ))
「ggpattern」パッケージパッケージの使用は、V3.5.0以降のベースggplot2 GEOMでパターン/グラデーションフィルを直接使用できることを強くお勧めします。 patternFill() wraps grid::pattern()およびpatterngrob（）であり、 ggplot2を使用してgridpatternパターンを直接使用する1つの方法です。
library( " ggplot2 " , warn.conflicts = FALSE )
library( " gridpattern " )
pal <- grDevices :: palette()
herringbone <- patternFill( " polygon_tiling " , type = " herringbone " , fill = pal [ 2 ])
truncated_hexagonal <- patternFill( " polygon_tiling " , type = " truncated_hexagonal " , fill = pal [ 3 ])
pythagorean <- patternFill( " polygon_tiling " , type = " pythagorean " , fill = pal [ 4 ])
df <- data.frame ( trt = c( " a " , " b " , " c " ), outcome = c( 2.3 , 1.9 , 3.2 ))
ggplot( df , aes( trt , outcome )) +
geom_col( fill = list ( herringbone , truncated_hexagonal , pythagorean ))
PeacePackrを使用すると、カスタムGrob関数を使用して、ゲームピースの外観を完全にカスタマイズできます。 {piecepackr} pp_shape()などのさまざまな便利な関数が搭載されており、カスタムGrob関数を使用してカスタムゲーム作品の作成を容易にします。 {gridpattern}を搭載したpp_shape()オブジェクトのpattern()メソッドを使用して、均一なポリゴンタイルで満たされた「パターン化された」チェッカーを作成する例を次に示します。
library( " grid " )
library( " gridpattern " )
library( " piecepackr " )
tilings <- c( " hexagonal " , " snub_square " , " pythagorean " ,
" truncated_square " , " triangular " , " trihexagonal " )
patternedCheckerGrobFn <- function ( piece_side , suit , rank , cfg ) {
opt <- cfg $ get_piece_opt( piece_side , suit , rank )
shape <- pp_shape( opt $ shape , opt $ shape_t , opt $ shape_r , opt $ back )
gp_pattern <- gpar( col = opt $ suit_color , fill = c( opt $ background_color , " white " ))
pattern_grob <- shape $ pattern( " polygon_tiling " , type = tilings [ suit ],
spacing = 0.3 , name = " pattern " ,
gp = gp_pattern , angle = 0 )
gp_border <- gpar( col = opt $ border_color , fill = NA , lex = opt $ border_lex )
border_grob <- shape $ shape( gp = gp_border , name = " border " )
grobTree( pattern_grob , border_grob )
}
checkers1 <- as.list(game_systems() $ checkers1 )
checkers1 $ grob_fn.bit <- patternedCheckerGrobFn
checkers1 <- pp_cfg( checkers1 )
x1 <- c( 1 : 3 , 1 : 2 , 1 )
x2 <- c( 6 : 8 , 7 : 8 , 8 )
df <- tibble :: tibble( piece_side = c( " board_face " , rep_len( " bit_back " , 24L )),
suit = c( 6L , rep(c( 1L , 3L , 4L , 5L ), each = 6L )),
rank = 8L ,
x = c( 4.5 , x1 , rev( x1 ), x2 , rev( x2 )),
y = c( 4.5 , rep(c( 1 , 1 , 1 , 2 , 2 , 3 , 6 , 7 , 7 , 8 , 8 , 8 ), 2 )))
pmap_piece( df , cfg = checkers1 , default.units = " in " )
