Hello. Does anyone know of an existing function that takes a list in the form of: Plot1 Species1 Abundance1 Plot1 Species2 Abundance2 Plot2 Species1 Abundance1 Plot2 Species3 Abundance3 . . . PlotN SpeciesN AbundanceN and translates into a matrix in the form of Species1 Species2.... SpeciesN Plot1 Abundance1 Abundance2... AbundanceN Plot2 Abundance1

Hi, I have had some troubles using doubleYScale. No matter what I try, I cant manage to change the color of the y-axis in the end. I have to produce a black and white plot. There is also something I do not understand regarding fontfamilyj="serif" when using it in: strip=strip.custom() Maybe someone has a better idea for defining which line and dots belong to which y-axis when not using

I'm attempting to use xyplot() within a for() loop to plot the relationship between a DV and a series of predictor variables, split by 2 conditioning variables. However, xyplot() does not "seem" to be recognized within the for() loop; I don't receive any error message, but nothing is plotted and a plotting device is not opened. When I use the generic function plot(),

I was wondering if somebody could explain why I get different results here: >treats[,2]<-as.factor(treats[,2]) >treats[,5]<-as.factor(treats[,5]) >treats[,4]<-as.factor(treats[,4]) #there are 'c' on more days than I have 'h2o2', where treats[,4] is the day. I only want 'c' that correspond to the same days that I have a 'h2o2' also.

Dear colleagues, What did I not understand ? ->my intention I want to create a new variable: In plain language: If someone is taking anithypertensive treatment (med.hyper==1) table(med.hyper) med.hyper 0 1 472 97 I want to subtract 5 mmHg (rr.dia.2m-5) from the measured diastolic blood pressure (rr.dia.2m) if not treated - the value of the measured diastolic blood pressure should

Dear R users, A have a dataframe (matrix) with two collumns (plot, and diameter (d)). I want all diameters values for different combination of plots. For example I want all d values for all posible combination, 100C2 (all d values for plot 1 with all d values in the plot 2.......with all d values from plot 1 with all d values from plot 100, ...... with all d values from plot 99 with all d values

estimados, ajusté una superficie de respuesta con el paquete "rsm" de R y hago un grafico 2D de la superficie de respuesta con contour(), pero como el argumento de esta función es la superficie de respuesta ajustada y ésta se ha ajustado codificando las variables, de acuerdo a la recomendación de la documentación del paquete rsm, obtengo un gráfico con los ejes en unidades codificadas

I''ve been testing ZFS since it came out on b27 and this week I BFUed to b30. I''ve seen two problems, one I''ll call minor and the other major. The hardware is a Dell PowerEdge 2600 with 2 3.2GHz Xeons, 2GB memory and a perc3 controller. I have created a filesystem for over 1000 users on it and take hourly snapshots, which destroy the one from 24 hours ago, except the
