cscale

Continuous scale

Description

Continuous scale

Usage

cscale(x, palette, na.value = NA_real_, trans = identity_trans())

Arguments

`x`	vector of continuous values to scale
`palette`	palette to use. Built in palettes: `area_pal`, `brewer_pal`, `dichromat_pal`, `div_gradient_pal`, `gradient_n_pal`, `grey_pal`, `hue_pal`, `identity_pal`, `linetype_pal`, `manual_pal`, `rescale_pal`, `seq_gradient_pal`, `shape_pal`, `viridis_pal`
`na.value`	value to use for missing values
`trans`	transformation object describing the how to transform the raw data prior to scaling. Defaults to the identity transformation which leaves the data unchanged. Built in transformations: `asn_trans`, `atanh_trans`, `boxcox_trans`, `date_trans`, `exp_trans`, `hms_trans`, `identity_trans`, `log10_trans`, `log1p_trans`, `log2_trans`, `log_trans`, `logit_trans`, `modulus_trans`, `probability_trans`, `probit_trans`, `pseudo_log_trans`, `reciprocal_trans`, `reverse_trans`, `sqrt_trans`, `time_trans`, `yj_trans`.

Examples

with(mtcars, plot(disp, mpg, cex = cscale(hp, rescale_pal())))
with(mtcars, plot(disp, mpg, cex = cscale(hp, rescale_pal(),
  trans = sqrt_trans())))
with(mtcars, plot(disp, mpg, cex = cscale(hp, area_pal())))
with(mtcars, plot(disp, mpg, pch = 20, cex = 5,
  col = cscale(hp, seq_gradient_pal("grey80", "black"))))
