Question regarding the dcast function

Hi,

I am having a problem with installing the dcast function in R 3.5.3

Here is the message that I am getting when trying to install it:
install.packages("dcast")
Installing package into ?C:/Users/marie/Documents/R/win-library/3.5?
(as ?lib? is unspecified)
Warning message:
package ?dcast? is not available (for R version 3.5.3)

Hi,

dcast() is a function, not a package, so R can't find it in the package archive.

You need to install the package that contains it. Probably you want reshape2

install.packages("reshape2")

Hi

You shouldn't use HTML formating unless you want to surprise us with weird and messy email.

function dcast is in data.table and/or in reshape2 packages. For both

install.packages("data.table")
install.packages("reshape2")

followed by
library(data.table)
library(reshape2)

should be enough to make function dcast available.

Maybe you could spent some time reading R-intro docs.

Cheers
Petr
