[R] Is this a bug in quantmod::OpCl?

OpCl works on xts objects but not on quantmod.OHLC objects. Is this a bug? Example error: x.Date <- as.Date("2003-02-01") + c(1, 3, 7, 9, 14) - 1 set.seed(1) x <- zoo(matrix(runif(20, 0, 1), nrow=5, ncol=4), x.Date) q <- as.quantmod.OHLC(x,c("Open","High","Low","Close")) # error OpCl(q) #> Erro

Re: [R] R-dvel [robustness Simulation study of 2 sample test on several combination of factors ]

You have quite a few mistakes in your example. The code below works for me - you can wrap it in a function if you like. I think you will need a lot more practice before you can write something like this in R as you are missing close braces and haven't really worked out the difference between the nu

Re: [R] Heatmap Colnames

Hi Nils, I don't have the GMD library, but this looks like some axis labels are being ignored to avoid overlapping. If heatmap.3 uses base graphics you can probably get your labels by passing empty strings to heatmap.3 and then displaying the axis with staxlab (plotrix). Jim On Wed, Apr 6, 2016

Don't give a factor to as.Date. Convert it to character first, or avoid letting it become a factor in the first place by using the stringsAsFactors =FALSE option to the read.table function or its related functions. -- Sent from my phone. Please excuse my brevity. On April 5, 2016 4:53:56 PM PD
