Hi again,
Thank you all for your support. I would love to have a graph in which two
variables are contemporary showed. For example a histogram and a curve
should be the perfect choice. I tried to use twoord.plot() but I am not
sure I understand how to manage the the arguments lx, ly, rx, ry... Anyway
these are my data:
nat_af
rel.abund rel.freq
MOTU2 0.003 0.083
MOTU4 0.029 0.167
MOTU6 0.033 0.167
MOTU7 0.023 0.083
MOTU9 0.009 0.083
MOTU11 0.042 0.250
MOTU14 0.069 0.083
MOTU16 0.059 0.167
MOTU17 0.034 0.083
MOTU18 0.049 0.083
MOTU19 0.084 0.333
MOTU20 0.015 0.083
MOTU21 0.059 0.083
MOTU22 0.032 0.167
MOTU23 0.142 0.250
MOTU24 0.031 0.083
MOTU25 0.034 0.083
MOTU29 0.010 0.083
MOTU30 0.011 0.083
MOTU33 0.004 0.083
MOTU36 0.034 0.333
MOTU34 0.182 0.417
First column is the relative abundance of the given MOTU and second column
is the relative frequency of the same MOTU.
Hi Gian,
You can do this in twoord.plot like this (data is named "nat_af" and the
first column is labeled "label"):
twoord.plot(1:22-0.2,nat_af$rel.abund,1:22+0.2,nat_af$rel.freq,
type=c("bar","bar"),lylim=c(0,0.19),rylim=c(0,0.43),halfwidth=0.2,
main="Abundance and frequency",ylab="Abundance",rylab="Frequency",
xticklab=rep("",22))
staxlab(1,at=1:22,labels=nat_af$label,cex=0.8,srt=45)
Jim
