Graphs in R

Program 6- Write a R program to demonstrate various types of graphs

SOURCE CODE:

# Create sample data

x <- c(1, 2, 3, 4, 5)

y <- c(2, 4, 6, 8, 10)

par(mfrow = c(2, 2))

# Plot a basic line graph

pts <- c(2,3,4,6,8)

 plot(pts, type = "o", col = "blue", lwd = 2, main = "Simple Line Graph", xlab = "X-axis", ylab = "Y-axis")

# Add points to the graph

points(pts, col = "red", pch = 16)

barplot(c(3, 5, 2, 7, 4), names.arg = c("A", "B", "C", "D", "E"), col = "orange", main = "Bar Plot", xlab = "Categories", ylab = "Values")

plot(x, y, col = "green", pch = 18, main = "Scatter Plot", xlab = "X-axis", ylab = "Y-axis")

boxplot(x, col = "blue", names = "X", main = "Box Plot", xlab = "Variables", ylab = "Values")

# Use awk to calculate characters, words, and lines

awk '{

    # Count characters

    ccount += length;

    # Count words

    wcount += NF;

    # Count lines

    lcount += 1;

    }

END {
