Use the example function, <code>my.mean()</code> distributed in the most recent R tutorial materials to calculate the mean of the variable (column) named <code>x</code> in your dataset. Now, write your own function to calculate the median of <code>x</code>. Be ready to walk us through how your function works! | Use the example function, <code>my.mean()</code> distributed in the most recent R tutorial materials to calculate the mean of the variable (column) named <code>x</code> in your dataset.

Load your vector from [[Statistics_and_Statistical_Programming_(Fall_2020)/pset1|Problem Set #1]] (Week 3) again (you might want to give it a new name) and perform the same cleanup steps you did in PC2.5 and PC2.6 last week (recode negative values as missing and log-transform the data). | Load your vector from [[Statistics_and_Statistical_Programming_(Fall_2020)/pset1|Problem Set #1]] (Week 3) again (you might want to give it a new name) and perform the same cleanup steps you did in PC2.5 and PC2.6 last week (recode negative values as missing and log-transform the data). | ||
===PC5. Compare two vectors=== | |||
Compare the vector <code>x</code> from Problem Set #1 with the first column (<code>x</code>) of the data you imported for Problem Set #2 (the current dataset you just imported from a .csv file). They should be similar, but are they really the same? Write R code to demonstrate your answer. | |||
