Change Axis Scales in Base R
To change the axis scales on a plot in base R Language, we can use the xlim() and ylim() functions. The xlim() and ylim() functions are convenience functions that set the limit of the x-axis and y-axis respectively. This function takes a vector as an argument which contains the values of lower axis limit and higher axis limit.
Syntax: plot( df$xaxis, df$yaxis, xlim, ylim)
where,
- df: determines the data frame in use.
- xaxis and yaxis: determine the axis variables for plotting.
- xlim: determines the vector that contains x-axis limits.
- ylim: determines the vector that contains y-axis limits.
Example: Basic example where plot axis limits are set from 0 to 2 for the x-axis and from 18 to 20 for the y-axis.
R
# create sample data frame sample_data <- data.frame(x=rnorm(100), y=rnorm(100)+20) # create plot with custom axis scales plot(sample_data$x, sample_data$y, xlim=c(0,2), ylim=c(18,20)) |

Convert axis scales to log scale:
To convert the axis scale log scale in the base R plot, we use the log argument of the plot() function. The log argument converts the given axis into its log scale alternative. This helps us in visualizing the skew data frames.
Syntax: plot( df$xaxis, df$yaxis, log)
where,
- df: determines the data frame in use.
- xaxis and yaxis: determine the axis variables for plotting.
- log: determines the axis which has to be converted in log scale.
Example: Basic example where the x-axis has been converted to its log scale alternative.
R
# create sample data frame sample_data <- data.frame(x=rnorm(100), y=rnorm(100)+20) # create plot with log x-axis scale plot(sample_data$x, sample_data$y, log='x') |
Output:
