If you go back to the result ofnames(financials)command you would see that few column names start with the same string. Columns we particularly interested in here start with word “Price”. Following R command using dplyr package will help us subset these two columns by writing as little cod...
As you can see, the RStudio console has returned the “Error in .subset(x, j) : invalid subscript type ‘list'” after executing the previous R code. The reason for this is that we have tried to extract data frame columns using a list object. ...

Example 1: Basic Barplot in R In Example 1, I’ll show you how to create a basicbarplotwith the base installation of the R programming language. First, we need to create a vector containing the values of our bars: values<-c(0.4,0.75,0.2,0.6,0.5)# Create values for barchart ...
Our boxplot suggests the second subset differs significantly, but we don’t have any concrete proofs. Here comes the best part - you can calculate ANOVA in R with a single function call! Let’s see how next. ANOVA in R With a Built-In Function We’ll work with the same dataset - ...
