Hi, I am working on categorical data with column as disease name(categaory). My input data is [1] Acute lymphoblastic leukemia (childhood) [2] Adiponectin levels [3] Adiponectin levels [4] Adiponectin levels [5] Adiponectin levels [6] Adiponectin levels [7] Adiposity [8] Adiposity [9] Adiposity [10] Adiposity [11] Age-related macular degeneration [12] Age-related macular degeneration [13] Aging (time to death) [14] Aging (time to event) [15] Aging (time to event) [16] Aging (time to event) [17] Aging (time to event) [18] AIDS [19] AIDS [20] AIDS ..... when i use table command, i get [,1] Acute lymphoblastic leukemia (childhood) 1 Adiponectin levels 5 Adiposity 4 Age-related macular degeneration 2 Aging (time to death) 1 ...... But i need to sort this table by frequency and need to plot a histogram with lable first column (e.g. Adiposity , Age-related macular degeneration as bar name). How can i do it?
Hi Manesh, The freq function (prettyR) returns a vector (or a list of vectors if more than one variable is passed) with the same information as the table function. However, freq orders the table in descending frequency by default. Jim
