R Programming Interview Questions Programming Beginner 1.Given data related to specific parameter for a country for a particular year is mentioned in Table 1. Provide an approach or write a program function using R to reshape the data in the way it is expected in Table 2 which is the desired layout. Explain briefly with your response.Table 1 Given input data 2.Given sample data below in table 1 has 4 columns including a date column in Col4. Provide an approach using separate function in R to convert the data to be reflected in desired layout as provided in Table 2. Explain briefly.Table1 Input data layout 3.Given below is sample input dataset and the code snippet. When we execute the code mentioned in Figure2 using the dataset in Figure1, is the desired output same as input data Explain with your response.Figure1 input dataset 4.When to use the following functions apply, lapply, sapply, tapply in R Explain. 5.Are the following code snippets same or different Explain why to support your response.flightsmutate1 flights mutatespeeddistanceairtime60 selectcarrier,arrdelay,speedflightsmutate2 flights selectcarrier,arrdelay,speed mutatespeeddistanceairtime60 6.We have a sample dataset related to pollution which can be described as below. How do we use R functions to come up with median and variance of that dataset. Secondly, what changes to the code snippet that you need to perform to add another information which will display the number of observations in the dataset. 7. What is the difference between n and ndistinct functions in R Explain with an example. 8. What is tidy data in R Explain with an example. Advanced 1.What is the difference between and 2. Which function is used to derive new variables using the dplyr package in R from existing variables Explain with an example. 3.What does kable perform in R Lets say if we use the airlines sample dataset and perform below operations in R console, do we expect any differences or are they same 4.Consider flights dataset in R. How can you find out how many flights go from a particular source to a particular destination The flights dataset looks like below.
