Dear list-members! I am using OpenWRT (www.openwrt.org) on two accesspoints. Within OpenWRT, the wireless interface and the ethernet interface are bridged to one interface (br0). Those two accesspoints are standing quite far from one another. Their WLAN-cells do not cross each other, meaning I have an area in between the two accesspoints, where there is no accesspoint of the two accessible: a

Hi, I am R beginner and am trying to figure out how to generate a complete list of species for every point, visit, and year. The code below is close but does not give me a list of species for every point, visit, and year in my data set. spplist<-unique(sumPtCt$Species) spplength<-length(spplist) Pointlist<-unique(sumPtCt$Point) Pointlength<-length(Pointlist)

Hi, I am trying to identify duplicate values in a column in a date frame. The duplicated function identifies the duplicate rows in the data frame but it only does this for the second record, not both records. Is there a way to mark both rows in the data frame as TRUE? dfA$dups<-duplicated(dfA$Value) dfA Site State Value dups 929 VA 73 FALSE 929 VA 73 TRUE 930 VA 76 FALSE 930 VA 76 TRUE 931

Hi, I have a dataset in which I would like to select rows based on matching conditions and return the maximum value of a variable else return one row if duplicate counts exist. My dataset looks like this: PGID PTID Year Visit Count 6755 53121 2009 1 0 6755 53121 2009 2 0 6755 53121 2009 3 0 6755 53122 2008 1 0 6755 53122 2008 2 0 6755 53122 2008 3 1 6755 53122 2009 1 0 6755 53122 2009 2 1 6755

Hi, I am relatively new to R and I am trying to figure out how to select rows of my data based on a condition. For example in the dataset below multiple observers recorded data at the same point on the same date and the data was recorded on separate rows, but I only need one of the rows of data. Is it possible to use grep to search for rows that have matching PtName and Date and then select the
