HI everyone
I have a table containing 20 columns, one of the columns has a mixtures of cells containing only numbers and other cells containing numbers and letters, like this:
23
23
243q
435
426yy5756
78443
2445
78789
6dfg546
kj45
cvb
3456tt
I want to get a subset of my table based on the above column, where we only include the cells containing numbers only, ie deleting any row with a cell in the above column that contains a number. The column itself is stored now as Factor
any help is greatly apreciated
