I knew it would be something simple. Thanks for catching that, Martyn. Billy -- View this message in context: http://r.789695.n4.nabble.com/Loop-stopping-after-1-iteration-tp3532988p3533041.html Sent from the R help mailing list archive at...

R 2.11.1 on Mac OS X. I didn't see the Note. -- View this message in context: http://r.789695.n4.nabble.com/computing-functions-with-Euler-s-number-e-n-tp3655205p3668849.html Sent from the R help...

Didn't mean to snub you guys, Hugo and David. I didn't see your posts before. Thanks for the advice. -- View this message in context: http://r.789695.n4.nabble.com/Loop-stopping-after-1-iteration-tp3532988p3533217.html Sent...

I resolved this issue. It appears that "^" won't work for this case, but "**" worked. I can't find any reference to this, but where "^" seems to be used to raise a value to a numerical function, "**" is used for...

One thing I should have mentioned before is that "pds_gagehandles" is a character vector that contains the site names that I am interested in. An example of a site name is "saho". So with with the paste function, I...

I solved this in two ways: 1. "**" was necessary to raise (-dummy + 1) to the power of B. "^" doesn't work here, for some reason. 2. I needed to use "as.complex" which greatly simplified my code and produces the...

Thanks for catching that, Sarah. It seems like the problem was that I was using the c() function to combine terms (including W) that I was adding to a data frame. This caused R to convert the numeric W to...

Hi, I am running a correlation analysis on a temporal dataset. I was wondering if you would receive the same tau and p values running the function: MannKendall(x), where x is the dependant variable that changes with time as...

Geoff, I think you could write an if loop to solve this. You could write: for(i in 1:num_obs){ if(DAYS[i]=='Monday'){ DF$DAYS.BETWEEN[i]<-1 } } Where 'num_obs' is the total number of temperature observations...

Hi all, Forgive me for this basic question. I've been doing some research and haven't been able to figure out how to best do this yet. I have 75 variables defined as vector time series. I am trying...

Also, I tried changing a line to store W as numeric: sample_info<-c(pds_gagehandles[i],p,as.numeric(sample_W)) But it is still sorting incorrectly: > W_table[order(W_table$as.numeric.W.),] pds_gagehandles.i. p...

Hi all, I am attempting to run PCA on a matrix (nrow=66, ncol=84) using 'prcomp' (stats package). My data (referred to as 'Q' in the code below) are separate river streamflow gaging stations (columns) and peak instantaneous discharge...

David and Josh, Thank you for the suggestions. I have attached a file ('q_values.txt') that contains the values of the 'Q' variable. David -- I am attempting an 'S' mode PCA, where the columns are actually the cases (different...
