In gggenes: Draw Gene Arrow Maps in 'ggplot2' Description Usage Arguments Details Aesthetics See Also Examples. View source: R/geom_gene_arrow.R. Description. geom_gene_arrow() draws genes as arrows, allowing gene maps to be drawn. Usage

North symbols are included in the plot with the annotation_custom function, which do not works when used together with an empty call to ggplot (see last example). When it is convenient to use an empty call to ggplot, use north2 instead. Aliases. north2.

Usage arrows(x0, y0, x1 = x0, y1 = y0, length = 0.25, angle = 30, code = 2, col = par("fg"), lty = par("lty"), lwd = par("lwd"), ) Arguments geom_segment() draws a straight line between points (x, y) and (xend, yend). geom_curve draws a curved line. See the underlying drawing function grid::curveGrob() for the parameters that control the curve. The main map can also be enhanced with the north arrow and scale bar using the ggsn package.

#' Spatial-aware north arrow #' #' @param height,width Height and width of north arrow #' @param pad_x,pad_y Padding between north arrow and edge of frame #' @param rotation Override the rotation of the north arrow (degrees conterclockwise) #' @param style A grob or callable that produces a grob that will be drawn as the north arrow.

space: a small space between arrow and text. vjust: vertical adjustment, set to 0 to align with the bottom, 0.5 for the middle, and 1 (the default) for the top. seg_len: length of the arrow segment. arrow_len: length of the arrow. arrow_type: type of the arrow. font_size: font size.

The idea is really basic : we create two polygons for the scale bar, we add some text above, and we draw an arrow. That’s it. Otherwise, just pass them as arguments to annotation_north_arrow().

North arrows are added using the annotation_north_arrow() function, and scalebars can be added using annotation_scale(). These functions are “spatial-aware”, meaning they know where north is and what the distance is across the plot.

automatic scalebar addition function is listed below. The example works. A common addition to any spatial plot are a north arrow and a scale bar. I've searched online for a straightforward way to add those to a ggplot plot. I then decided to give a go myself. A crude first attempt for an automatic scalebar addition function is listed below.

Details. geom_gene_label() uses the 'ggfittext' package to fit text to genes. All text drawing options available in ggfittext::geom_fit_text() (growing, reflowing, etc.) are also available here. For full details on how these options work, see the documentation for ggfittext::geom_fit_text().. Standard 'ggplot2' aesthetics for text are supported (see Aesthetics).

Se hela listan på r-spatial.org Drawing gene arrows with geom_gene_arrow() geom_gene_arrow() is a ggplot2 geom that represents genes with arrows. The start and end locations of the genes within their molecule(s) are mapped to the xmin and xmax aesthetics respectively. These start and end locations are used to determine the directions in which the arrows point. Also, I tried spplot but despite I like the label axis format I can't add a scalebar and a north arrow, perhaps because of the raster's longlat projection. Share.
