$ operator is invalid for atomic vectors in HH R

Question

I am trying to generate this graph. Using this package

Following is in datafile

code:

eqdata <- read.table(datafile , header = T,sep=",")
#eqdata <- as.data.frame(eqdata)
eqdata1 <- hh(eqdata)

aed <- logrelrisk(eqdata1)

p <- ae.dotplot(aed, A.name="TREATMENT A (N=216)",B.name="TREATMENT B (N=431)")

Output: Error in ae$SAE : $ operator is invalid for atomic vectors Calls: logrelrisk

any help much appreciated.

Answer 1

Cut out the eqdata1 <- hh(eqdata) line. From the ?hh documentation, this function merely returns the path to the specified file, and is thus not a data.frame, as is required by logrelrisk().

eqdata <- read.table(datafile , header = T,sep=",")
#eqdata <- as.data.frame(eqdata)
# eqdata1 <- hh(eqdata)

aed <- logrelrisk(eqdata)

p <- ae.dotplot(aed, A.name="TREATMENT A (N=216)",B.name="TREATMENT B (N=431)")
