Hi All. I have problem with generating series of plots. In detail:
I have file of data which I insert into dataframe: data<-read.table("file.txt", header=TRUE, sep=" ") Data in this file are prepared in such a way, that the header of each column has a value of one of examined parameter - something like that: X Y 01.0 01.1 01.2 01.5 01.6 02.0 1 11.74 10.71 16 16 16 1 16 16 2 12.43 10.97 16 16 16 1 1 16 3 11.63 11.92 16 16 1 1 16 1 I need to generate a XY plot for each column (I need to observe changes in context of parameter (header names) change). Each column has a few values and it is reflected in point's shape (pch). I'm doing this using (example for fourth column): plot(data$X~data$Y,main="Parameter, 01.1", pch=data$01.1) In this way I have different point shape and value of parameter in main plot label. For the first few columns it is: plot(data$X~data$Y,main="Parameter, 01.0", pch=data$Pr.01.0) plot(data$X~data$Y,main="Parameter, 1.1", pch=data$Pr.01.1) plot(data$X~data$Y,main="Parameter, 1.2", pch=data$Pr.01.2) I use it together with par(mfrow=c(3,2)), so I have 6 plots at a time. My question is: How can I automate creation od plots? The values in headers are not a series - they should be read from header, because I can not prepare them in one or two "for" loops. (1.2 and next can be 1.5 next 2.0 next 2.7 -certain values are not predictable) The problem is that I have a lot of columns (now 57, sometimes - about 100, without initial filtering - more than 300). Now I manually rewrite parameter value and copy line "plot(...)". It is very laborious work, and I think it can be automated. Does anyone has an idea how can I use data frame headers as parameters in plot (legend and parameter of pch)? I'm sure that it will be "for" loop - I know how many plots I need, but what inside "for" (combining data frame header and plot parameter)?
