2. (Dataset: gss. Variables: income06, wtss.) The gss dataset contains income06. In this exercise you use cut2 (with the "g=" argument) to collapse gss$income06 into four equal-size groups. Follow these steps: (i) Create a numeric version of gss$income06. Name the numeric version, gss$income06.n. (ii) Collapse gss$income06.n into four equal-size groups. Name the collapsed variable, gss$income06.n4. (iii) Give gss$income06.n4 these level names: "Low," "MedLow," "MedHigh," "High", (iv) Redefine gss$income06.n4 as an ordered factor. A. Run freq on gss$income06.n4. Print the bar chart of gss$income06.n4. B. Run printC on the frequency distribution of gss$income06.n4. Copy/paste the frequency distribution into a word processing document. Print the frequency table
