[R] setting up R -- VM Fusion, WIndows7

Hi, As i need R to speak to Bloomberg (and big only runs on windows), i'm running windows 7 via VM Fusion on my mac. I think i am having permission problems, as i cannot use install.packages, and cannot change .libPaths via either a .Rprofile, or Profile.site. I've posted more detail in this sup

[R] fine control of plots after use of layout(matrix ...

Sir, I would like to create a combined line-bar plot, with the line up top and bar plot below, but with the x-axes suppressed on the topmost plot, the line and bar plot areas joined by a common line, and the x-axes (of dates) joined to the bottom part of the bar plot. i have been able to format t

Re: [R] fine control of plots after use of layout(matrix ...

Thanks. The solution i have been persuing is reading Murrell - and trying to figure out grid / Viewport commands. Is it best to stay in the base graphics package if possible? Sent from my iPad On 04/06/2012, at 6:20 AM, Sarah Goslee wrote: > On Sun, Jun 3, 2012 at 4:05 PM, Matthew John

[R] what does .indexDate() do - R::xts

Dear R experts, I am learning the very useful XTS package, but cannot figure out the purpose of some commands. in particular, the .indexDate() command does not work as expected. say: x <- timeBasedSeq('2010-01-01/2010-01-02 12:00') x <- xts(1:length(x), x) then i can subset on date as follows:

Re: [R] what does .indexDate() do - R::xts

thanks. i think i understand: the difference is that the first command converts my 'searched-for' date to a number and matches it, but the second does not? On 13 June 2012 12:58, Joshua Ulrich wrote: > On Tue, Jun 12, 2012 at 9:48 PM, Matthew Johnson > wrote: > > Dear R

[R] templated use of aggregate

Dear R-help, I have an xts data set that i have subset by date. now it contains a date-time-stamp, and two columns (price and volume traded): my objective is to create tables of volume traded at a price - and i've been successfully using aggregate to do so in interactive use. say the data looks

Re: [R] templated use of aggregate

mand could be made to be: px_ym1 count vol_ym1 1 97.90 11 408 2 97.89 10 208 where we have the price traded, the number of trades (a count of px_ym1 / mn[,1], and the sum of vol_ym1 (mn[,2]). thanks and best regards matt johnson On 13 June 2012 15:06, David Winsemius wrote: >

ethods for “zoo” objects do not work if the index entries in ‘order.by’ are not unique mnz[, 1] mnz[, -1] 197.90 408 297.89 208 So is this a bug in XTS? thanks for your patience mj On 13 June 2012 15:53, David Winsemius wrote: > > On Jun 13, 2012, at 9:38 AM, Matthe

[R] Writing data including NAs to access using RODBC

Hi, I have run into a problem writing data using RODBC. The dataframe i have read in from access includes some NAs. I have put the data into an xts object, manipulated the data, and would now like to append two columns of the manipulated data to the original table in access. I cannot append the d

[R] Aligning time series

Sir, I have large data sets of economic indicators and would like to align them to a reference series - say the unemployment rate or industrial production. Is there a canned routine that returns the optimal lead / lag according to some (or a variety) of algorithims? not all series will be of the
