problem with comparing a part of string with whole string
Hi ,
i just attached one file to this mail which contains one modal of my data
and there i have to search for the rows which contains "SPECIMENTYP %in%
"ADIPOSE TISSUE""
and the rows which contains " "PRESERVED" in ORGCHARRES
for that i tried with
" r<-subset(rr,SPECIMENTYP %in% "ADIPOSE TISSUE" & grep("IN
DIAMETER",rr$ORGCHARRES),select=c(SPECIMENTYP,ORGCHARRES))"
but i got only the rows having "ADIPOSE TISSUE" in "SPECIMENTYP"
can anyone suggest any of the way for comparision of this type
thanks in advance

Hi all, I got one problem with comparing strings like if any string is like "*RIGHT, EPICARDIUM: FOCUS, GRAY-WHITE, SINGLE, APPROX 0.6 CM IN
DIAMETER*."
and i have to compare "*GRAY-WHITE*" with the above string or otherwise i have to compare " *TUMOR BENIGN*" this
string
with "*MEDULLRY TUMOR BENIGN,TYP PHEOCHROMOCYTOMA*" i tried with split and compare but its not working
Work for regular expressions? vec="*RIGHT, EPICARDIUM: FOCUS, GRAY-WHITE, SINGLE, APPROX 0.6 CM IN DIAMETER*." test="GRAY-WHITE" regexpr(test, vec) [1] 28 attr(,"match.length") [1] 10 Regards Petr
