a) The process of representing data graphically to identify patterns and insights
b) A method for storing data
c) A tool for statistical analysis
d) A technique for cleaning data
Answer:
a) The process of representing data graphically to identify patterns and insights
Explanation:
R data visualization is the process of representing data graphically to identify patterns, trends, and insights that might not be immediately apparent in raw data. Visualization techniques help in exploring data, communicating findings, and making informed decisions. R offers a wide range of functions and packages for creating various types of plots, charts, and graphs.
# Example of data visualization in R
data <- c(10, 20, 30, 40, 50)
plot(data, type = "o", col = "blue", xlab = "X-Axis", ylab = "Y-Axis", main = "Simple Line Plot")In this example, a simple line plot is created using the plot() function in R. Data visualization is a crucial part of data analysis, as it allows you to quickly interpret data and communicate results effectively.
