Hi, I have this dataset where columns z1.3 and z1.4 are full of NA's. I want to perform some calculations in the remaining columns, but after doing this, I want to recontruct the original matrix.

I have this challenge of converting a bit of html into an image file and then shrinking it into a thumbnail. The shrinking part shouldn''t be too bad, but what advice can you give on converting the html to the image? My thinking is that I will need to convert it to postscript or latex and then convert it to an image from there. Is there an easier / better approach? Michael

Gracias, Juan --

Estimados compañeros tengo el siguiente problema: quiero poner etiqueta a los valores de una variable. He creado una lista que se llama geren que tiene 194 valores distintos.
