Hello everyone, when I run the "unique" command on my data frame, it deletes the majority of duplicate rows, but not all of them. Here is a sample of my data. How do I get it to delete all the rows? 6 -115.38 32.894 195 162.94 D 8419 D 7 -115.432 32.864 115 208.91 D 8419 D 8 -115.447 32.773 1170 264.57 D 8419 D 9 -115.447 32.773 1170 264.57 D 8419 D 10 -115.447 32.773 1170

Does anyone know of any R code for computing partial cross-correlation? I have examples of cross correlation functions (ccfs) that are not smooth but rather consist of a peak of several high values in consecutive lags, with sharp drops on either side. This indicates that y(t) is a function of some average of x(t-tau) at the set of lags tau over which the ccf is high. I could sort out these

Hello everyone, When I run a for loop I noticed that the looping variable gets assigned the last value in the loop: For example, if I let h=200, and I run for(i in 1:h), i gets the value 200. What's wrong here? -- -Tony [[alternative HTML version deleted]]

Hi, The first column in as.matrix(x) has extra spaces (" "), which I don't want. Is there a way not to generate those spaces? Regards, Peng > x=data.frame(x=1:10,y=letters[11:20]) > as.matrix(x) x y [1,] " 1" "k" [2,] " 2" "l" [3,] " 3" "m" [4,] " 4" "n" [5,] " 5"

I am having a hard time interpreting the phase and coherency plots. x is two timeseries that occur at the same time i.e. a b 1 11.2 12.3 16 11.3 12.4 31 11.4 12.5 46 11.5 12.6 ...etc even though my example is does not show this they are oscillating at more or less the same frequency just shifted by t=x (imagine two sine waves offset with the 2nd sine

I'm trying to do this in several ways but havent had any result. Im asked to install python, or perl.... etc. Can anybody suggest a direct, easy and understandable way?

This is has been bugging me for a long time. Nobody around me seems to have this problem. I hope someone on the forum could help me. When I generate a R graph and want to bring the image into Word. I cannot copy and paste it like many of my classmates can do. The "Select" in Edit menu have all options grayed out. So what I ended up doing is to save it as pdf file and bring it

I'm plotting the following (stripped of inessentials) xyplot(sd ~ distance | wshed,data=sdvar.df,scales=list(x=list (log=TRUE),y=list(log=TRUE))) sdvar.df is a data frame, sd and distance are numeric, wshed is an ordered factor trying to replicate the action of log="xy" in plot() The plot works fine but the axis values at the ticks are in scientific notation, e.g. 10^1.5,

Greetings Though I have months in chronological order in my data table, the data were sampled every other month (i.e., February, April, June, August, October, December), every time I try to plot them (on the x-axis) they are plotted in alphabetical order. What am I missing? Cheers Kurt *************************************************************** Kurt Lewis Helf, Ph.D. Ecologist EEO

I want to add identifier column (Date) to a time series data frame. I want to name the "Date" column be from 1 to 30 every 1440 rows. Say I have a data like this (I simply my actual data here): $dat ID Var 1 1 2 4 3 6 4 7 5 7 6 8 How can I add identifier column (Date) from 1 to 3 every 2 rows and have output like this: ID

Hi, Following my earlier posts about having problems performing a PCA, I have worked out what the problem is. The problem lies within the PLINK to gds conversion. It seems as though the SNPs are imported as "samples" and in turn, the samples are recognised as SNPs: >snpsgdsSummary("chr2L") Some values of snp.position are invalid (should be > 0)! Some values of

Dear R-list, I have a partly comma separated partly underscore separated string that I am trying to parse into R. Furthermore I have a bunch of them, and they are quite long. I have now spent most of my Sunday trying to figure this out and thought I would try the list to see if someone here would be able to get me started. My data structure looks like this, (in a example.txt file) Subject
