Psychrometric coordinates

Usage

coord_psychro(
  tdb_lim = NULL,
  hum_lim = NULL,
  altitude = NULL,
  units = NULL,
  mollier = NULL,
  expand = FALSE,
  default = TRUE,
  clip = "on"
)

Arguments

tdb_lim: A numeric vector of length-2 indicating the dry-bulb temperature limits. Should be in range [-50, 100] degree_C [SI] or [-58, 212] degree_F [IP]. If NULL, trained data ranges will be used when available, otherwise a default display range will be used. Default: NULL.
hum_lim: A numeric vector of length-2 indicating the humidity ratio limits. Should be in range [0, 60] g_H20 kg_Air-1 [SI] or [0, 350] gr_H20 lb_Air-1 [IP]. If NULL, trained data ranges will be used when available, otherwise a default display range will be used. Default: NULL.
altitude: A single number of altitude in m [SI] or ft [IP]. Default: 0.
units: A string indicating the system of units chosen. Should be either "SI" or "IP".
mollier: If TRUE, a Mollier chart will be created instead of a psychrometric chart. Default: FALSE.
expand: If TRUE, the default, adds a small expansion factor to the limits to ensure that data and axes don't overlap. If FALSE, limits are taken exactly from the data or xlim/ylim. Giving a logical vector will separately control the expansion for the four directions (top, left, bottom and right). The expand argument will be recycled to length 4 if necessary. Alternatively, can be a named logical vector to control a single direction, e.g. expand = c(bottom = FALSE).
default: Is this the default coordinate system? If FALSE (the default), then replacing this coordinate system with another one creates a message alerting the user that the coordinate system is being replaced. If TRUE, that warning is suppressed.
clip: Should drawing be clipped to the extent of the plot panel? A setting of "on" (the default) means yes, and a setting of "off" means no. In most cases, the default of "on" should not be changed, as setting clip = "off" can cause unexpected results. It allows drawing of data points anywhere on the plot, including in the plot margins. If limits are set via xlim and ylim and some data points fall outside those limits, then those data points may show up in places such as the axes, the legend, the plot title, or the plot margins.

Examples

ggpsychro() +
    coord_psychro(tdb_lim = c(10, 35), hum_lim = c(0, 25))


ggpsychro(units = "IP", altitude = 1000) +
    coord_psychro(
        tdb_lim = c(50, 100),
        hum_lim = c(0, 140),
        units = "IP",
        altitude = 1000
    )


ggpsychro(mollier = TRUE) +
    coord_psychro(
        tdb_lim = c(0, 50),
        hum_lim = c(0, 30),
        mollier = TRUE
    )
