problem with comparing a part of string with whole string

Imagine the following data of noises that people make, and you want to know
who makes the noise "blub."

data=data.frame(rbind(c("blah, boo, blub"),c("blabber, baeh,
blib"),c("quack, cheer, blub")))
names(data)=c("noises")
data

searchTerm="blub"

#The first gives a list of all noises that people make
#who also make the "blub" noise (among others)
data$sound[grep(searchTerm,data$noises)]

# This gives the index (row) number of the observation  
# of who makes the "blub" noise
which(data$noises==data$noises[grep(searchTerm,data$noises)])

Is that what you want?

Betreff: Re: [R] 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

can any one suggest how can i compare these type of Strings

thanks in advance
