Subsetting to unique values
I want to take the first row of each unique ID value from a data frame. For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.

getting data associated with coordinates in a spatial data frame
If I know the specific coordinate in a spatial data frame, how can I access the data at that coordinate? My coordinates are labeled "x" and "y" in a data.frame "e". The data is in column "leachate". I want to say, basically: e$leachate@coordinates(2,3<mailto:e$leachate@coordinates(2,3>). Thanks, Daniel [[alternative HTML version deleted]]

side by side histogram after splitting data by year
Hi everyone, I'm looking to produce a side-by-side histogram of the number of trips taken by jays with a particular number of acorns after accounting for year (year "one" and year "two"). I know this involves indexing first then creating a histogram but I'm not sure how I'd do this. I want to explore the possibilities that jays are altering their strategies in

Repeated Measures
Hi R Gurus, I am more or less a beginner with R. I have searched your FAQ, manuals, and the archives of this list for an answer to this question, unsuccessfully. I commonly do analysis of chemical characteristics of soils, by depth intervals (e.g. 0-100 mm, 100-200, 200-300, etc), comparing two soil profiles that have received some treatment (effluent). In Genstat I can handle this problem

[PATCH v2 0/8] vsock/virtio: optimizations to increase the throughput
While I was testing this new series (v2) I discovered an huge use of memory and a memory leak in the virtio-vsock driver in the guest when I sent 1-byte packets to the guest. These issues are present since the introduction of the virtio-vsock driver. I added the patches 1 and 2 to fix them in this series in order to better track the performance trends. v1:
