| log.axis {heR.Misc} | R Documentation |
Function to add a nice log base-10 axis
to a plot, with major/minor tics and optional gridlines.
See log.tics for details on generating tic positions.
log.axis(side, limits, exp.format=TRUE,
grid=TRUE, grid.lty="solid", grid.col="lightgray", grid.lwd=1,
major=TRUE, minor=TRUE, label.minor=FALSE,
minor.cex=0.75, major.cex=1, ...)
side |

exp.format |
whether or not labels should be in exponential format |
grid |
logical, draw gridlines or not |
grid.lty |
line type for gridlines |
grid.col |
color for gridlines |
grid.lwd |
line width for gridlines |
major |
logical, draw major tics or not |
minor |
logical, draw minor tics or not |

More arguments to pass to the axis function |
You can add log-axis tics and labels to the 1. Bottom, 2. Left, 3. Top, or 4. Right side of the plot.
This function will add tics/labels in units of 10$^i$ as major tics, where i = ..., -2, -1, 0, 1, 2, ..., e.g., 0.1, 1, 10
Minor tics will be added as integer multiples of the major tics, e.g., as 0.2, 0.3, 0.4, ..., 0.9, for tics betwen 0.1 and 1
Invoked for the effect of adding tics and tic labels to an existing plot.
