Imagine you are working with a data file "gdp_eco80001.csv" that has two columns: date and gdp. (This question does not have a real data file attached). The goal of the code below is to: 1. load the "gdp_eco80001.csv" dataset 2. calculate the average GDP, and 3. create a line plot showing GDP over time. Choose the correct options in the dropdown boxes. library( [ Select ] openai tidyverse pwt10 data.table gapminder ) df <- [ Select ] data load_data read_data load_csv readRDS read_csv ("gdp_eco80001.csv") df %>% [ Select ] summarise filter stat arrange select calculate (average = mean(gdp)) df %>% ggplot(aes(x = date, y = gdp)) + [ Select ] graph geom_bar line_graph geom_point chart geom_line line ()

Step-by-Step Analysis
The question presents a code snippet task where you load a dataset, compute an average GDP, and create a line plot of GDP over time. We will evaluate each option in the order of the code blocks and justify why the chosen options make sense, while clarifying why the alternatives would not fit.
Option 1 (library([ Select ] tidyverse openai …)):
- The correct choice is tidyverse. The subsequent pipe-based data manipulation and ggplot usage in the snippet align with the tidyverse style, which also prov......Login to view full explanationLog in for full answers

Suppose you have given a subset of our North American Stock Market dataset in a data frame called compdf. There are all the 50 columns. Similar to our North American Stock Market dataset, gvkey and fyear combination uniquely identifies each observation in compdf. If you execute length(unique(compdf$loc)), you are returned 7. If you execute compdf %>% group_by(gvkey) %>% summarise(count = n()) , all the values under count column are 20. Suppose you executed the following code successfully. df1 <- compdf %>% group_by(loc, fyear) %>% summarise(stat1 = mean(at, na.rm = TRUE), stat2 = max(stat1)) df1 should have [Fill in the blank] rows and 4 columns. If the information provided in the question is not sufficient, please type "not enough information".
Suppose you had a dataset (assigned to data frame object called df). You know that it has 100 observations with a single numerical column called a. All observations for a are equal to 100. You then run the following code: df$b <- df$a df$a <- 0 mean(df$a != df$b) What did R output when the entire code was executed successfully? [Fill in the blank]
Suppose df has 30 rows with 3 numeric columns named d, e, and f. When you executed length(which(df$d >= 5)) the output returned is 20. Then, you executed df <- df %>% mutate(d = if_else(d >= 5, 5, 0)) TRUE/FALSE: When you execute the following line of code, the result returned can be less than 10. length(which(df$d == 0))
Suppose you had a dataset (assigned to data frame object called df). df has 100 observations with a single numerical column called col1. col1 value of each observation is equal to 10. You then run the following code: df$col2 <- df$col1 df$col1 <- 0 mean(df$col2) What did R output when the entire code was executed successfully? [Fill in the blank]
