Hi,
Given the following R code:
library(pryr)
data <- array(dim = c(5))
for(x in 1:5)
{
data[x] <- as.integer(x * 2)
}
add = address(data) # save address of "data"
for(x in 1:5)
{
data[x] <- as.integer(0)
}
if (add == address(data))
{
print("Address did not change")
}
else
{
print("Address changed")
}
If one runs this code, message "Address changed" is printed. However, if one
comments line "data[x] <- as.integer(0)" the address of "data" does not change
and message "Address did not change" is printed instead. Why? The datatype of
the array should not change with this line and hence no need for R to convert
the array to a different type (and have the array's address changing in the
process).
Thank you!
