Dear Sekhar, I'm sorry that you're experiencing these problems. Although you haven't said so directly, I assume that you aren't able to use install.packages() to install *any* CRAN packages, not just the Rcmdr package. Downloading and unpacking the Rcmdr zip file doesn't install the package.

Dear Sarah, I don't entirely follow what you did, but my guess is that you installed the Rcmdr and FactoMineR packages but not the RcmdrPlugin.FactoMineR package. If that's the case, then install the RcmdrPlugin.FactoMineR, e.g., via install.packages("RcmdrPlugin.FactoMineR") and try again.

Your R is quite old -- newest version is at least 3.2.3 . As a general rule, you should first upgrade to the current versions of both R and packages **before posting**, as the posting guide requests I believe. This is precisely to avoid problems like this. If this fails to resolve your problems,

The Posting Guide mentioned at the bottom of every message on the list has many helpful tips. One of these is that you should install the latest version of R before asking for help on the list. v2.15.1 is quite old in Internet time. BTW, if this your troubles are specific to running on

Re: [R] Calculate average of many subsets based on columns in another dataframe

A strategy: 1. Convert your dates and intervals to numerics that give the days since a time origin. See as.POSIXlt (or ** ct for details and an example that does this). Should be fast... 2. Use the findInterval() function to get the interval into which each date falls. This **is** "vectorized"

Thanks David, Bert, >From what I'm reading on ?findInterval, It may not be workable because of overlapping date ranges. findInterval seems to take a series of bin breakpoints as its argument. I'm currently exploring data.table documentation and will keep thinking about this. Just on David's

Most of the mass of that distribution is within 3e-100 of 2. You have to be pretty lucky to have a point in sequence land there. (You will get at most one point there because the difference between 2 and its nearest neightbors is on the order of 1e-16.) seq(-2,4,len=101), as used by default in

You could try pulling some of the repeated subscripting operations, especially the insertions, out of the loop. E.g., values <- observations[,"values"]; date <- observations[,"date"] ; groups$average <- vapply(seq_len(NROW(groups)), function(i) mean(values[date >= groups[i, "start"]
