Read API for the ecdb

Description

Read ecdb into data.frame. This can be accomplished by either specifying the range of alpha,gamma or the cartesian product of alpha,gamma point by point, or both. If both are specified, it follows a similar logic as plot how x,y is scoped by xlim,ylim.

Usage

## S3 method for class 'ecdb'
read(
  object,
  alpha = NULL,
  gamma = NULL,
  alim = NULL,
  glim = NULL,
  cusp = 0,
  polar_ext = FALSE
)

read(
  object,
  alpha = NULL,
  gamma = NULL,
  alim = NULL,
  glim = NULL,
  cusp = 0,
  polar_ext = FALSE
)

## S4 method for signature 'ecdb'
read(
  object,
  alpha = NULL,
  gamma = NULL,
  alim = NULL,
  glim = NULL,
  cusp = 0,
  polar_ext = FALSE
)

Arguments

object	an object of ecdb class
alpha, gamma	numeric vectors of points for cartesian product
alim, glim	length-two numeric vectors of min and max range
cusp	numeric. Type of cusp. Only 0 and 1 are allowed. If cusp=1, read cusp data on the critical line. Reading cusp data must be done from the alpha side. Default: 0.
polar_ext	logical, for polar coordinate extension: R, theta, angle. Default: FALSE.

Value

The data.frame from ECDATTR table.
