forestplot (version 3.1.3)

getTicks: Ticks for plot axis

Description

Gets the ticks in a formatted version. This is since I'm not always that fond of just pretty(1:10/5). In exponential form the ticks are determined from the 2-base, meaning that you get an intuitive feeling for when the value is doubled.

Usage

getTicks(low, high = low, clip = c(-Inf, Inf), exp = FALSE, digits = 0)

Value

vector Returns a vector with the ticks

Arguments

low

lower bound, can be a single number or a vector

high

upper bound - optional, you can just have all data in the low variable

clip

if the ci are clipped

exp

If the value should be in exponential form (default)

digits

Number of digits - used in exp mode

Details

This function is far from perfect and I recommend specifying yourself the ticks that you want.

Examples

test_data <- data.frame(
  coef = c(2, 0.5),
  low = c(1.5, 0.05),
  high = c(3, 0.75),
  boxsize = c(0.5, 0.5)
)

# Exponential form where the exponent base i 2 for easier understanding
getTicks(
  low = test_data$low,
  high = test_data$high,
  clip = c(-Inf, Inf),
  exp = TRUE
)

# Non exponential form with using pretty
getTicks(
  low = test_data$low,
  high = test_data$high,
  clip = c(-Inf, Inf),
  exp = FALSE
)


# A very simple example
getTicks(1:5 * 2.33,
  exp = FALSE
)

# A slightly more advanced exponential version
getTicks(1:10 * .33,
  digits = 2,
  exp = TRUE
)
