Question 8: Use the function cut to split the number of reviews to five different groups. # Warning: Removed 1474 rows containing missing values (geom_point). Stat_smooth(method = "auto") # `geom_smooth()` using method = 'gam' and formula 'y ~ s(x, bs = "cs")' # Warning: Removed 1474 rows containing non-finite values (stat_smooth). Ggplot(google_play, aes(x = log(Reviews), y = Rating)) + # Warning: Transformation introduced infinite values in continuous x-axis # `geom_smooth()` using method = 'gam' and formula 'y ~ s(x, bs = "cs")' # Warning: Removed 1474 rows containing non-finite values (stat_smooth). Scale_x_log10() # Warning: Transformation introduced infinite values in continuous x-axis Ggplot(google_play, aes(x = Reviews, y = Rating)) +
Bonus: is there a transformation which you can use on the x-axis, for the chart to make more sense? What is it? Use log(reviews) or use ggplot2’s scale function for a log.Currently the graph doesn’t make any sense. Do you see anything wrong with the chart? Very few observations on the higher end of Reviews, but these are “significant” apps.“lm” can also work, but the real deal is coming right up…
Loess is too sensitive and yields really unreasonable results. If that doesn’t make sense - keep exploring. What did you choose and why? Sometimes its a good guess to go with the default, in this case “auto”.

Would you say that some categories of Android Ver should be grouped together? Depends.What was the latest android version when the file was generated? Probably 8.0+.What is the order by which the columns are sorted? Lexicographic (abc…)īuild a chart that shows which android versions are supported by each app.Theme( = element_text(angle = 45, hjust = 1)) Ggplot(data = google_play, mapping = aes(x = Category)) + ggplot(data = google_play, mapping = aes(x = Category)) +

Note that the last part of the code ( theme(.)) is meant to rotate the x axis labels, for better readability. Question 5: Complete the code below and answer the questions that follow. The Category variable represents the app’s category. To numeric: using string manipulation: Size (the app’s size, perhaps also Installs). To factor: Category, Installs, Type, Content Rating, Genres, Android Ver. Question 4: What variables were read as character but you think that you would be better off if they were tranformed to a different type? Look at the dataset using glimpse(?), notice that most columns were read as characters and a few as double. ) # Warning: package 'tidyr' was built under R version 3.5.3 # Warning: package 'dplyr' was built under R version 3.5.3 google_play_raw % You are going to load the file directly from our course’s repository, using the following command: suppressMessages( It however doesn't work very well, and give me missing heat boxes.In this exercise we will work with a file downloaded from the competition website kaggle.
Where x, y and z are my treatment condition order. I've tried this command scale_x_discrete(limits=c("Y","X","Z")) How do I override this/keep the data in the same order as in my original csv file? In this case, I'm trying to specify the order of "Treatment". I just want to be able to specify the order of the labels on the x axis. I'm not too familiar with commands and programming and I'm relatively new at this. Scale_fill_gradient(low = "black",high = "red") +Ī = element_text(size = base_size, angle = 90, hjust = 0, colour = "black"),Ī = element_text(size = base_size, hjust = 1, colour = "black")). Here is my code below: p<-ggplot(data,aes(Treatment,organisms))+geom_tile(aes(fill=S))+ I'm trying to make a heatmap using ggplot2 using the geom_tiles function
