Good people, I need to alter each member of a list that matches a certain pattern. However, I need the whole list back, in its original order. So Cases[] on its own doesn't do the trick. Here is a toy example that is analogous to my real problem: Put an asterisk on each value that is 10 or greater in the following list. list = RandomSample[Range[20], 20] Out[1]= {19, 16, 5, 13, 10, 20, 1, 3, 18, 8, 9, 6, 12, 7, 4, 15, 11, 14, 2, 17} I came up with two ways to do this. However, I feel like I may be missing a simpler, single function way to do this. Method 1: If[# > 9, SuperStar[#], #] & /@ list Out[2]= {SuperStar[19], SuperStar[16], 5, SuperStar[13], SuperStar[10], SuperStar[20], 1, 3, SuperStar[18], 8, 9, 6, SuperStar[12], 7, 4, SuperStar[15], SuperStar[11], SuperStar[14], 2, SuperStar[17]} Method 2: ReplacePart[list, Table[{Position[list, x_ /; x > 9][[i, 1]] -> Map[SuperStar, Cases[list, x_ /; x > 9]][[i]]}, {i, Length[Cases[list, x_ /; x > 9]]}] // Flatten] Out[3]= {SuperStar[19], SuperStar[16], 5, SuperStar[13], SuperStar[10], SuperStar[20], 1, 3, SuperStar[18], 8, 9, 6, SuperStar[12], 7, 4, SuperStar[15], SuperStar[11], SuperStar[14], 2, SuperStar[17]} Am I missing a more straightforward way to do this? Thanks, Jason Jason Ebaugh
