Dear R users,
I am trying to do the forest plot follow the function given on web. However,
the order of the tests has been sorted alphabetically. I would prefer
keeping the order as data frame input so that I can group and compare (from
the graph) the target immune NS1, IgG and IgM (where SD, BioRad, Pb etc are
the brand names)
> d
x y ylo yhi
SD.NS1 SD.NS1 43.23250 38.25736 48.20764
BioRad.NS1 BioRad.NS1 57.31750 54.28494 60.35006
Pb.NS1 Pb.NS1 56.21563 53.14092 59.29033
SD.IgG SD.IgG 62.26750 60.65677 63.87823
Iq.IgG Iq.IgG 78.80917 78.34625 79.27209
Merlin.IgG Merlin.IgG 62.46333 60.68995 64.23672
Pb.IgG Pb.IgG 57.51500 56.94022 58.08978
SD.IgM SD.IgM 76.90417 75.61221 78.19613
Iq.IgM Iq.IgM 79.45917 78.73032 80.18801
Merlin.IgM Merlin.IgM 64.50167 60.30376 68.69958
Pb.IgM Pb.IgM 65.38667 61.81591 68.95742
AFRIMS AFRIMS 88.29958 84.84922 91.74995
I am currently using the code as suggested on web:
credplot.gg<- function(d){require(ggplot2)
p <-
ggplot(d,aes(x=x,y=y,ymin=ylo,ymax=yhi))+geom_pointrange()+coord_flip()+
xlab('RDT tests')+ylab('Sensitivity')
return(p)}
d <-
data.frame(x=names(ragama.meta)[2:13],y=xx[2:13],ylo=xx[2:13]-1.96*ss[2:13],
yhi=xx[2:13]+1.96*ss[2:13])
credplot.gg(d)
How should I correct this so that I can fix the order of the rapid tests the
way I put in.
Thank you in advance.
