Limit the points for the "basic" plots

[suzannejin]

Hi! Is there a way to limit the points to plot in "basic" mode?? Otherwise, it takes too much time in order to compute the plots...

Precrec does not provide a method for controlling supporting points when the mode is set to basic. Nonetheless, there are several ways to reduce the computational time of generating plots.

1. Use R's default plot function
2. Specify type = "l" to change points to lines
3. Specify metrics

Metrics can be one or a combination of error, accuracy, specificity, sensitivity, precision, mcc and fscore.

library(precrec)
library(ggplot2)

# Generate a dataset with 5 different models (P:1000, N:1000)
samp <- create_sim_samples(1, 1000, 1000)
mdat <- mmdata(samp[["scores"]], samp[["labels"]], modnames = samp[["modnames"]])
mdat

# Calculate basic metrics
sspoints <- evalmod(mdat, mode = "basic")

# 1. R's default plot
plot(sspoints)

# 2a. type = "l" 
plot(sspoints, type="l")

# 2b. type = "l" with ggplot
autoplot(sspoints, type="l")

# 3a. Specify metrics
autoplot(sspoints, type="l", "accuracy")
autoplot(sspoints, type="l", c("error", "accuracy"))

# 3a. Specify metrics with ggplot
autoplot(sspoints, type="l", "accuracy")
autoplot(sspoints, type="l", c("error", "accuracy"))
