Probably variations of these will solve your problem :

> formatC(pi * 10^(-7:-3), format = "f", digits = 10)
[1] "0.0000003142" "0.0000031416" "0.0000314159" "0.0003141593" "0.0031415927"

> formatC(pi * 10^(-7:-3), format = "fg", digits = 10)
[1] "0.0000003141592654" "0.000003141592654"  "0.00003141592654"  
[4] "0.0003141592654"    "0.003141592654"
