r - prediction applied to whole data -

hi doing prediction data.if use data.frame throws folloing error.

input(bedrooms="2",bathrooms="2",area="1000") specified different   types fit  here program  input <- function(bedrooms,bathrooms,area) { delhi <- read.delim("delhi.tsv", na.strings = "")  delhi$lnprice <- log(delhi$price) heddel <- lm(lnprice ~ bedrooms+ area+ bathrooms,data=delhi) valuepred = predict (heddel,data.frame(bedrooms=bedrooms,area=area,bathrooms=bathrooms),na.rm = true) final_prediction = exp(valuepred) final_prediction } 

if remove data.frame predicts value on data.i got following output.

       1          2          3          4          5          6          7    15480952   11657414   10956873    6011639    6531880    9801468   16157549           9         10         11         14         15         16         17    10698786    5596803   14688143   20339651   22012831   16157618   26644246  

but needs display 1 value only.

any idea how resolve this..any appreciated

sharon, want make prediction specific values of bedroom, bathroom , area, putting them in character rather numeric values. causing error seeing. when remove data.frame statement predict, produce predictions based on data set used build model, i.e. delhi.

try

input(bedrooms=2,bathrooms=2,area=1000)
