Excel Trend Function
Hi: I have a dataset and need to interpolate for missing days. In Excel I either average from sampled days from above and below the missing days or use the TREND function to make up for the missing values. I have been reading about na.approx, is this function similar to the TREND function? Which is the best recommendable way to make up for missing data? Here's my dataset: weeks 17,18,26 and 46

summing up colum values for unique IDs when multiple ID's exist in data frame
I have data.frame's with IDs and multiple columns. B/c some of IDs showed up more than once, I need sum up colum values to creat a new dataframe with unique ids. I hope there are some cheaper ways of doing it... Because the dataframe is huge, it takes almost an hour to do the task. Thanks so much in advance!

another question on shapefiles and geom_point in ggplot2
Manuel: I changed your variable names from x to 'long' and y to 'lat' on the riqueza_out.csv file. The code below should do what you want. Also, since the legend title is kind of long, I broke it down into three lines so you can see more plot area. I am cc'ing the other groups so more people use it if needed. library(rgdal) library(ggplot2) library(sp) library(maptools)

aftreg vs survreg loglogistic aft model (different intercept term)
Hi, I'm estimating a loglogistic aft (accelerated failure time) model, just a simple plain vanilla one (without time dependent covariates), I'm comparing the results that I obtain between aftreg (eha package) and survreg(surv package). If I don't use any covariate the results are identical , if I add covariates all the coefficients are the same until a precision of 10^4 or 10^-5 except
