Re: [R] using lapply and split to plot up subsets of a vector
Hi again, I have spent the last couple of days trying to build a function that will allow me to add to the multiple plots that I created with your advice. I have changed to plot(ln.o2con~lnbm,data=df) in my function and this works fine. On an individual plot I can fit quantile regressions using "quantreg" but I can't figure out how to plot these lines on the multiple graphs that I can create with plot. a<- function(df)abline(rq(ln.o2con~lnbm,tau=0.99,data=df)) b<- lapply(split(one,one$sp.id),a) print(b) c<- function(df)abline(rq(ln.o2con~lnbm,tau=0.01,data=df)) d<- lapply(split(one,one$sp.id),c) print(d) e<- function(df)abline(rq(ln.o2con~lnbm,tau=0.01,data=df)) f<- lapply(split(one,one$sp.id),e) print(f) My knowledge of building functions in R is poor and I can't figure out how to combine these functions so that I may plot each graph individually with the correct ablines for each fit. I can get the lines to plot but only on one graph. Again I would be grateful for any help, I really like using R but it is the bottleneck in my analysis and things are moving very slow while I try to tackle this steep learning curve and become a more familiar with how to use R the best way.

[R] using lapply and split to plot up subsets of a vector
Hi, I would like to be able to plot data from each of the sp.id on individual plots. At the moment I can plot all the data on one graph with the following commands but I cannot figure out how to get individual graph for each sp.id. i<- function(df)plot(lnbm,ln.o2con,data=df) j<- lapply(split(one,one$sp.id),i) I have searched on the net and through the threads here but I cannot find anything that matches what I am trying to do. Any help would be greatly appreciated.

[R] simple loop(?) analysing subsets
Hi All,
I have a large data set with many columns of data. One of these columns is a
species identifier and the remainder are variables such as temperature or
mass. Currently I am carrying out a single regression on subsets of the data
set, e.g. separated data sets with only the data from one species at a time.
I have been searching for a thread that will help me to understand how best
to repeat this process for each different species identifier in that
variable column. I can’t seem to find one that is similar to what I am
trying to do. It might be the case that I am not looking for the right thing
or that I do not fully understand the process.
How do I run a simple loop that produces a regression for each species as
identified in the variable species id, which is one column in the large data
set that I am using?
Simple regression that I wish to repeat
data<- read.table("…/STUDY.txt",header=T)
names(data)
model<- with(data,{lm(o2con~bm)})
summary(model)
sample data set
species id o2con bm
1 0.5 5
1 0.6 2
1 0.4 4
1 0.4 2
1 0.5 3
2 0.3 7
2 0.4 8
2 0.5 3
2 0.7 4
2 0.9 2
3 0.3 6
3 0.7 2
3 0.4 1
3 0.3 7
5 0.3 2
5 0.6 1
5 0.9 7
5 0.2 5
I would be very grateful for some help with this. I really like using R and
I can usually figure out what I want to do but I have been trying to figure
this out for a while now and I am getting nowhere.
Thank you.
