Hello, I am trying to use the plm package for panel econometrics. I am just trying to get started and load my data. It seems from most of the sample documentation that I need to use the pdata.frame function to get my data loaded. However, even after installing the "plm" package, my R installation cannot find the function. I am trying to follow the example in plmEN.pdf ( cran.mirroring.de/doc/vignettes/plm/plmEN.pdf )
library(plm)
Loading required package: kinship Loading required package: survival Loading required package: splines Loading required package: nlme Loading required package: lattice [1] "kinship is loaded" Loading required package: Formula Loading required package: MASS Loading required package: sandwich Loading required package: zoo Attaching package: 'zoo' The following object(s) are masked from package:base : as.Date.numeric
library(Ecdat) data(Hedonic) pdata.frame(Hedonic, "townid")
Error: could not find function "pdata.frame"
From here, I decided to try using plm.data, which worked
h2 <- plm.data(Hedonic, "townid")
However, doing a summary of the h2 object, it was not as in the plmEN.pdf example, meaning it did not show any information about the panel structure of the object. I would appreciate some help as to getting my data into a proper pdata.frame. Thank you, -stephen barr ========================================== Stephen J.
