The _comma ones set comma format for axis text and expand=c(0,0) (you need to set limits).

scale_x_percent(name = waiver(), breaks = waiver(),
minor_breaks = waiver(), labels = scales::percent, limits = NULL,
expand = c(0.01, 0), oob = censor, na.value = NA_real_,
trans = "identity", position = "bottom", sec.axis = waiver())

scale_y_percent(name = waiver(), breaks = waiver(),
minor_breaks = waiver(), labels = scales::percent, limits = NULL,
expand = c(0.01, 0), oob = censor, na.value = NA_real_,
trans = "identity", position = "left", sec.axis = waiver())

scale_x_comma(name = waiver(), breaks = waiver(),
minor_breaks = waiver(), labels = scales::comma, limits = NULL,
expand = c(0.01, 0), oob = censor, na.value = NA_real_,
trans = "identity", position = "bottom", sec.axis = waiver())

scale_y_comma(name = waiver(), breaks = waiver(),
minor_breaks = waiver(), labels = scales::comma, limits = NULL,
expand = c(0.01, 0), oob = censor, na.value = NA_real_,
trans = "identity", position = "left", sec.axis = waiver())

## Arguments

name The name of the scale. Used as axis or legend title. If waiver(), the default, the name of the scale is taken from the first mapping used for that aesthetic. If NULL, the legend title will be omitted. One of: NULL for no breaks waiver() for the default breaks computed by the transformation object A numeric vector of positions A function that takes the limits as input and returns breaks as output One of: NULL for no minor breaks waiver() for the default breaks (one minor break between each major break) A numeric vector of positions A function that given the limits returns a vector of minor breaks. One of: NULL for no labels waiver() for the default labels computed by the transformation object A character vector giving labels (must be same length as breaks) A function that takes the breaks as input and returns labels as output A numeric vector of length two providing limits of the scale. Use NA to refer to the existing minimum or maximum. same as in ggplot2 Function that handles limits outside of the scale limits (out of bounds). The default replaces out of bounds values with NA. If na.translate = TRUE, what value aesthetic value should missing be displayed as? Does not apply to position scales where NA is always placed at the far right. Either the name of a transformation object, or the object itself. Built-in transformations include "asn", "atanh", "boxcox", "exp", "identity", "log", "log10", "log1p", "log2", "logit", "probability", "probit", "reciprocal", "reverse" and "sqrt". The position of the axis. "left" or "right" for vertical scales, "top" or "bottom" for horizontal scales specify a secondary axis
