fn_LTGSI

Description

The scattering plot is generated without any labels or marks for the X-axis, which is very simple. A horizontal line is included with the threshold value, which serves as the basis for the figures that will be generated through the analysis, whether they are simple or compound figures.

A scatter plot of the y value by factor level across the x range also includes a horizontal dashed line representing the threshold value.

Colors are manipulated with the rgb() function of the grDevices package

The function requires defining:

  • x: A vector containing the values of the independent variable..
  • y: A vector containing the values of the dependent variable..
  • df: A data frame.
  • xl: A label for the X-axis.
  • yl: A label for the y-axis.
  • Icut: A threshold Value.
  • ylimit: A vector value with a minimum and maximum limit for y-axis.

fn_LTGSI

The function is included in the Repbio package Reproductive biology analysis.

#library(Repbio)

The function is detailed below.

fn_LTGSI <- function(x, y, df, xl, yl, Icut, ylimit){
  plot(x , y,
       col = rgb(0,0,0,1/4),
       xlab= xl,
       ylab= yl,
       pch= c(0,1,15,16,17,2)[as.numeric(df$Phase)],
       ylim= ylimit,
       xaxt="n"
      )

      abline(h= Icut,col="black",lty = 2)
}  # End function fn_LTGSI

Examples

Falta detallar el ejemplo.

 #  x <-x
 #  y <- y
 #  df <- tmp
 #  xl <- etiquetas[1]
 #  yl <- etiquetas[3]
 #  Icut <- 2.3
 #  ylimit <- c(0,45)
 # ejemplo <- fn_LTGSI(x, y, df, xl, yl, Icut, ylimit)
