geom_bump Creates a ggplot that makes a smooth rank over time. To change the 'smooth' argument you need to put it outside of the 'aes' of the geom. Uses the x and y aestethics.
Description
geom_bump
Creates a ggplot that makes a smooth rank over time. To change the 'smooth' argument you need to put it outside of the 'aes' of the geom. Uses the x and y aestethics.
Usage
geom_bump(
  mapping = NULL,
  data = NULL,
  geom = "line",
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  smooth = 8,
  direction = "x",
  inherit.aes = TRUE,
  ...
)
Arguments
| mapping | provide you own mapping. both x and y need to be numeric. | 
| data | provide you own data | 
| geom | change geom | 
| position | change position | 
| na.rm | remove missing values | 
| show.legend | show legend in plot | 
| smooth | how much smooth should the curve have? More means steeper curve. | 
| direction | the character x or y depending of smoothing direction | 
| inherit.aes | should the geom inherits aestethics | 
| ... | other arguments to be passed to the geom | 
Value
ggplot layer
Examples
library(ggplot2)
df <- data.frame(country = c(
  "India", "India", "India",
  "Sweden", "Sweden", "Sweden",
  "Germany", "Germany", "Germany",
  "Finland", "Finland", "Finland"),
year = c(2011, 2012, 2013,
2011, 2012, 2013,
2011, 2012, 2013,
2011, 2012, 2013),
rank = c(4, 2, 2, 3, 1, 4, 2, 3, 1, 1, 4, 3))
ggplot(df, aes(year, rank, color = country)) +
  geom_point(size = 10) +
  geom_bump(size = 2)
geom_sigmoid Creates a ggplot that makes a smooth rank over time. To change the 'smooth' argument you need to put it outside of the 'aes' of the geom. Uses the x, xend, y and yend aestethics. Make sure each sigmoid curve is its own group.

rank_sigmoid Creates a longer dataframe with coordinates for a smoothed line.
Description
rank_sigmoid
Creates a longer dataframe with coordinates for a smoothed line.
Usage
rank_sigmoid(x, y, smooth = 8, direction = "x")
Arguments
| x | vector | 
| y | vector | 
| smooth | smooth parameter. Higher means less smoothing | 
| direction | the character x or y depending of smoothing direction | 
Value
a data frame
sigmoid Creates a longer dataframe with coordinates for a smoothed line.
Description
sigmoid
Creates a longer dataframe with coordinates for a smoothed line.
Usage
sigmoid(x_from, x_to, y_from, y_to, smooth = 5, n = 100, direction = "x")
Arguments
| x_from | start x value | 
| x_to | end x value | 
| y_from | start y value | 
| y_to | end y values | 
| smooth | smooth parameter. Higher means less smoothing | 
| n | number of point that should be smoothed | 
| direction | the character x or y depending on direction of smoothing | 
Value
a data frame
