What is Geom_pointrange?

What is Geom_pointrange?

geom_pointrange: An interval represented by a vertical line, with a point in the middle.

What does Stat_summary do in R?

stat_summary() operates on unique x or y ; stat_summary_bin() operates on binned x or y . They are more flexible versions of stat_bin() : instead of just counting, they can compute any aggregate.

What is Geom_point in Ggplot?

The point geom is used to create scatterplots. The scatterplot is most useful for displaying the relationship between two continuous variables.

What is Stat_smooth in R?

stat_smooth() provides the following variables, some of which depend on the orientation: y or x. predicted value. ymin or xmin. lower pointwise confidence interval around the mean.

What is Mean_sdl?

mean_sdl computes the mean plus or minus a constant times the standard deviation. In the R code below, the constant is specified using the argument mult (mult = 1).

What does ggplot () do in R?

ggplot() initializes a ggplot object. It can be used to declare the input data frame for a graphic and to specify the set of plot aesthetics intended to be common throughout all subsequent layers unless specifically overridden.

What is Alpha ggplot2?

Alpha refers to the opacity of a geom. Values of alpha range from 0 to 1, with lower values corresponding to more transparent colors.

What is the difference between Geom_bar and Geom_histogram?

geom_bar() is for both x and y-values are categorical data — so there are spaces between two bars as x-values are factor with distinct levels. geom_histogram() is for one continuous data and one categorical data.

What does Geom_col do in R?

geom_col makes the height of the bar from the values in dataset.

Why is Coord_fixed () important in R?

coord_fixed forces a specified aspect ratio between the physical representation of the units on the axes. The ratio is 1 by default. It is important to fix the aspect ratio in this case because hwy and cty are measured in the same unit (miles per gallon).

What is stroke in ggplot2?

geom_point ) ggplot(data = mpg) + geom_point(mapping = aes(x = displ, y = hwy), stroke = 3, shape = 21) stroke adjusts the thickness of the border for shapes that can take on different colors both inside and outside.

What is the difference between Geom_smooth and Stat_smooth?

geom_smooth() and stat_smooth() are effectively aliases: they both use the same arguments. Use stat_smooth() if you want to display the results with a non-standard geom.

What does the Stat_smooth () function do?

Description. Aids the eye in seeing patterns in the presence of overplotting.

What is Median_hilow?

hilow computes the sample median and a selected pair of outer quantiles having equal tail areas. The smedian.hilow calculates the median and lower and upper quartiles according to a confidence interval.

What package is Dotplot in R?

dotplot function is from easyGgplot2 R package. An R script is available in the next section to install the package.
