Hello R experts,

I have go this data frame:

'data.frame':	1 obs. of  20 variables:
 $ Anno  : chr "PREVISIONI VS TARGET"
 $ OreTot: num 41
 $ GioTot: logi NA
 $ OrGTot: logi NA
 $ OreCli: num 99
 $ GioCli: logi NA
 $ OrGCli: logi NA
 $ OreFor: num -27
 $ GioFor: logi NA
 $ OrGFor: logi NA
 $ OreOrt: num -18
 $ GioOrt: logi NA
 $ OrGOrt: logi NA
 $ OreSpo: num -6
 $ GioSpo: logi NA
 $ OrGSpo: logi NA
 $ OreUff: num -7
 $ GioUff: logi NA
 $ OrGUff: logi NA
 $ temp  : num 0

Is there any way I can format the numeric fields so that I get a leading "+" whenever the value is > 0? In the specific case I would need something like:

'data.frame':	1 obs. of  20 variables:
 $ Anno  : chr "PREVISIONI VS TARGET"
 $ OreTot: num +41
 $ GioTot: logi NA
 $ OrGTot: logi NA
 $ OreCli: num +99
 $ GioCli: logi NA
 $ OrGCli: logi NA
 $ OreFor: num -27
 $ GioFor: logi NA
 $ OrGFor: logi NA
 $ OreOrt: num -18
 $ GioOrt: logi NA
 $ OrGOrt: logi NA
 $ OreSpo: num -6
 $ GioSpo: logi NA
 $ OrGSpo: logi NA
 $ OreUff: num -7
 $ GioUff: logi NA
 $ OrGUff: logi NA
 $ temp  : num 0

Thank you in advance,

Luca
