R tidyr - pivot_wider() (Long to Wide)
Long-format data stores observations in rows where each row represents a single measurement. Wide-format data spreads these measurements across columns. pivot_wider() from the tidyr package…

R tidyr - pivot_longer() (Wide to Long)
• pivot_longer() transforms wide-format data into long format by converting column names into values of a new variable, essential for tidy data analysis and visualization in R
R - reshape() - Wide to Long and Back
• The reshape() function transforms data between wide format (multiple columns per subject) and long format (one row per observation) without external packages
Pandas - Melt (Reshape Wide to Long)
• The melt operation transforms wide-format data into long-format by unpivoting columns into rows, making it easier to analyze categorical data and perform group-based operations
