[R] interaction plot and x axis
Dear all I am trying to make an interaction plot among 6 variables; e.g. PH to be in the x axis and the rest 5 variables in the y axis. The code that I am using is the below: The name of my file is e.g. spec so spec-read.csv(spec.csv) head (spec) str(spec) names-names(spec)[2:6] speclong - reshape(spec, idvar = id, varying = list(names), v.names=outcome,direction = long) speclong$time2-factor(speclong$time,labels=rep( ,5)) interaction.plot(speclong$PH,speclong$time2,speclong$outcome, xaxt=n, type=l, log=y, trace.label=,col=rainbow(8)) what I want is to change the labels of the x axis. If for example I don't use xaxt=n, by default it shows some values of PH e.g. 4.93, 5.97, 6.23, 6.47, 6.59, 6.77, 6.89, 7.35 but it don't show the ticks in each value. However I would like to define the x values e.g. 5.0, 5.5, 6.0, 6.5, 7.0. I used the xlim but it says error as well axis(1, at=c(5.0, 5.5, 6.0, 6.5, 7.0)) but still there is a problem. Does anyone know how I can define that? Thank you in advance.

[R] fitting a distribution to a ecdf plot
Dear all, I need to plot an cumulative distribution plot of a variable and then to fit a distribution to that, probably a weibull or lognormal. I have plotted the ecdf as plot(ecdf(x)) but I haven't managed to fit the distribution. I have as well attached the data. I would appreciate if you could help me on that. Thank you.

[R] how to change the margins of a plot area
Dear all, I am ploting two boxplot of two chemical variables using the format boxplot(Alkalinity, logAlkalinity, log=y, col=c(lightblue), lwd=0.6, boxwex=0.3) However when I plot like this, the distance between the two boxplots is very big and as well the distance of each boxplot from the plot area, left and right. How can I minimise that distance between the boxplots and as well the distance of each boxplot from the left and right margin of the plot area? Another question is that when I write in the above ylab=Concentration, I get in the y axis as well in each tick and a number. How can I not have this but only the text? Thank you.

[R] Uncertainty analysis
Dear all I would like to run in R an uncertainty/sensitivity analysis. I know that these two are performed together. I have a geochemical model where I have the inputs, the water variables (e.g. pH, temperature, oxygen ect) and as well an output of different variables. What I would like to do is to estimate the uncertainty that the output variables have considering the uncertainty of the input variables as well how the variations of my inputs contribute most to the variations of my output (probably though the sensitivity analysis). I was thinking perhaps with Monte Carlo analysis. Is there a way to do that? Thanks a lot.

[R] plot dates in x-axis
Hallo, I am trying to plot dates in x-axis. The format of my dates are in dd/mm/. At first I install zoo package. After R reads my file, I change the default format of dates to the format that I have, myfile-read.csv DATE-as.Date(DATE,format=%d/%m/%Y) up till now everything goes ok; when however I go and plot for example plot(DATE, Discharge) in the x-axis I only get the years, 1998, 2000, 2002... How can I see in the x-axis the whole format of the dates that I have e.g. 29/01/1998?

[R] Trendline and R square value
Hi I would like to display the trendline and the R-square value in a xy scatter in R. For example if I want to plot f vs g I add the trendline using the commands below library(quantreg) plot(f,g) abline(rq(g~f)) however I don't know how to display the R2 in the graph. Thank you in advance.

[R] Time plots
Dear all, I want to do some time plots and actually the dates are in the format of dd/mm/. So first I input my dataframe in R in a csv form. What I do is DF-read.csv(C:/Documents and Settings/DF.csv) DATE-as.Date(DATE, %d/%m/%Y) # to tell R that DATE column is indeed dates with(DF, plot(DATE,pH)) Until here it works fine, but I have the graph plotting only the points. What I want is to have a line (join these points) so to have a time plot. I have tried different commands such as lines(DATE,pH) or with(DF, lines(DATE,pH) but nothing works. What can I do?

[R] Boxplots with different variables and different ranges in R
Dear all, I am trying to make boxplots in one diagram but it is not working. Actually I have a large dataset, around 35 water quality variables with different units and of course in different ranges (some are orders of magnitude bigger than others). I want to produce one diagram with all the boxplots of the variables of my dataset. I tried these series of commands: oldpar - par(mfrow=c(1,ncol(R))) invisible(apply(R, 2,boxplot)) for (i in 1:ncol(R)) boxplot(R[,i], main=colnames(R)[i]) par(oldpar) (where R is the name of my dataset) The problem is that after the second command, there is an error in plot.new( ): figure margins too large. Is there a way to overcome this and put all my variables in a same diagram? I tried with less number of variables, but I had the same warning. Thank you very much for your time and help.

[R] Enquiries about time plots in R
Dear all, My name is Maria Lathouri and I am currently doing a PhD at Imperial College of London about time series of environmental variables in surface waters. I am trying to do some time plots with R but it seems that it is not working. The problem is that the time is not regular, for example, a small dataset can be seen below: Date pH 1/02/1998 5.5 5/03/1998 5 8/12/1998 6 1/02/1999 6.1 ... 08/10/20007.2 I have used the function plot(DATE, pH) and then lines(pH), but the line does not join the points. I have used many combinations, e.g. plot(DATE, pH) and then lines(DATE, pH), where I get a plot with full of lines inside or just plot(pH) and then lines(pH) where the line connects the points but in x-axis I do not have the DATE. It says Index from 0 to 80. Do you know if there is a function where I can have in x-axis the DATE (irregular dates) and in y-axis the variable with a continuous line, showing how it changes through time? I know that your time is valuable but I would appreciate it if you could help me. Thank you very much in advance for your time and help. I am looking forward to hearing from you.
