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.
