Starting with data preparation, topics include how to create effective univariate, bivariate, and multivariate graphs. In addition specialized graphs including geographic maps, the display of change over time, flow diagrams, interactive graphs, and graphs … R-selected species usually don't care for offspring, whereas k-selected species such as orangutans will provide care (orangutan offspring live with their mothers for up to eight years). Examples include rabbits, bacteria, salmon, plants such as weeds and grasses, etc. Many insects are r-selected. For example, ants can be considered r-selected. The frog is an R- selected species. The frog is an R -selected species for the following reasons: Frogs produce many small offsprings (High fecundity) - They produce thousands of little frogs on day one and most of them would die.

Step 2: Select data: Select GoingTo and DayOfWeek ; Step 3: Filter data: Return only Home and Wednesday ; We can use the hard way to do it: # Step 1 step_1 <- read.csv(PATH) # Step 2 step_2 <- select(step_1, GoingTo, DayOfWeek) # Step 3 step_3 <- filter(step_2, GoingTo == "Home", DayOfWeek == "Wednesday") head(step_3) Output: Customizing ggplot2 Graphs. Unlike base R graphs, the ggplot2 graphs are not effected by many of the options set in the par( ) function. They can be modified using the theme() function, and by adding graphic parameters within the qplot() function. For greater control, use ggplot() and other functions provided by the package. R-selected species usually don't care for offspring, whereas k-selected species such as orangutans will provide care (orangutan offspring live with their mothers for up to eight years).
