Fruit_Market<-data.frame(fruit=character(0),cost=numeric(0),quantity=integer(0))
You would have to create a data.frame by using only 0-length variables and it'll give you an empty data.frame.

You can either NA values
data.frame(fruit=NA, cost=NA, quantity=NA)[numeric(0), ]
Try this:
names <- c("fruit","cost","quantity") df <- data.frame() for (k in names) df[[k]] <- as.character()
You can use as.data.frame like this:
as.data.frame(x, row.names = NULL, optional = FALSE, …)
make sure row.names is NULL
as.data.frame is a good choice. For more detailed, have a look at the documentation.
Please try following code snippet.
df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender") colnames(df) <- x

Thanks.
Will the below code work to create a empty dataframe?
v=data.frame(fruit=NA, cost=NA, quantity=NA)
It show columns with no data in row.
fruit_Frame<-data.frame(Fruit=NA, Cost=NA, Quantity=NA)[-1,];
#thank me later or never
Hi,
You need to create a data frame with zero rows as shown below.
df <- data.frame(matrix(ncol = 3, nrow = 0)) x <- c("name", "age", "gender") colnames(df) <- x
