Read a .txt file that was created from readings of the Standing-Katz chart, then convert it to a .rda file and plot the curve for given Tpr. If no values are supplied, the function will plot the SK curve at Tpr=1.30, low Ppr.

getStandingKatzCurve(tpr = 1.3, pprRange = "lp", tolerance = 0.01,
  toView = FALSE, toSave = FALSE, toPlot = TRUE, ylim = c(0.2,
  1.2))

Arguments

tpr

Pseudo-reduced temperature curve in SK chart

pprRange

Takes one of two values: "lp": low pressure, or "hp" for high pressure

tolerance

rounding tolerance to avoid rounding readings that are in the middle of the grid. "tolerance" adds flexibility in deciding point closeness. Default value is 0.01.

toView

set to FALSE to prevent visualizing the dataframe

toSave

set to FALSE to indicate if the .rda file will not be saved to disk

toPlot

set to FALSE to indicate the dataset will not be plotted

ylim

minimum (0.2) and maximum (1.2) limits for the y-scale

Examples

# get SK curve for low-pressure chart getStandingKatzCurve()
# get SK curve for high-pressure chart getStandingKatzCurve(tpr = 1.3, pprRange = 'hp', toView = FALSE, toSave = FALSE)
