In ggplot2, we can use annotation_logticks together with scales::trans_breaks and scales::trans_format. Below is an example taken from the link above.

    library(ggplot2)

    a <- ggplot(msleep, aes(bodywt, brainwt)) +
      geom_point(na.rm = TRUE) +
      scale_x_log10(
        breaks = scales::trans_breaks("log10", function(x) 10^x),
        labels = scales::trans_format("log10", scales::math_format(10^.x))
      ) +
      scale_y_log10(
        breaks = scales::trans_breaks("log10", function(x) 10^x),
        labels = scales::trans_format("log10", scales::math_format(10^.x))
      ) +
      theme_bw()

    a + annotation_logticks() # Default: log ticks on bottom and left
