[R] How to force R to print 2 decimal places in column of a data.frame?

[Lesandro]

How to force R to print 2 decimal places in column of a data.frame? I tried to do so:

x = inp(format(rounf(inp$Tamanho, 2), nsmall = 2),)

where "INP" is data.frame and "Size" is the name of column. But has error:

Error in eval.with.vis(expr, envir, enclos) : 
  could not find function "inp"
