[R] using paste and "\" to create a valid filename

Sometimes even the easy stuff is difficult (for me)... I want to get input from different places to paste together an excel filename (so you know I'm using windows) that I can open with RODBC. I know about using double "\" since its an escape character, but I get either 2 or none, I can't get just one "\" where I need it. See example code below. I am using R 2.1.0, but plan to upgrade soon. Thanks in advance to anyone who can help.

rankPath <- "R:\New Ranks\SMC\SMC"				
rankDate <- "20050819"				
rankFile <- paste(rankPath,rankDate,".xls", sep="")
rankFile
[1] "R:New RanksSMCSMC20050819.xls"
rankPath <- "R:\\New Ranks\\SMC\\SMC"				
rankDate <- "20050819"				
rankFile <- paste(rankPath,rankDate,".xls", sep="")
rankFile
[1] "R:\\New Ranks\\SMC\\SMC20050819.xls"
