Dear all
I have some data with following structure in data frame.
dput(evid[1:2,c(2:4)])
evid <- structure(list(V2 = c("test vodivosti kalcin?tu",
"impregnace anatasov? pasty rozpra?ovac? su??rna"
), V3 = c("03.03.2017", "17.03.2017"), V4 = c("EICHLER
V?ra;#125",
"HO???LKOV? Jarmila;#119;#BERN?T Miroslav;#122;#OSTR?IL Marek;#60"
)), .Names = c("V2", "V3", "V4"), row.names =
9:10, class = "data.frame")
Each row in V4 column contain names followed by ;#xxx. I would like to separate
them like that
mena <- liche(unlist(strsplit(evid[2,4], ";#")))
here is function liche
liche <- function (x)
{
indices <- seq(along = x)
x[indices%%2 == 1]
}
and repeat each respective row of data frame for separated names like following
(which is only for one row)
temp<-evid[2,][rep(seq_len(nrow(evid[2,])), length(mena)),-4]
cbind(temp, mena)
V1 V2 V3

10.1 OSTR?IL Marek OSTR?IL Marek 1kalcinace BERN?T Miroslav
10.2 OSTR?IL Marek OSTR?IL Marek 1kalcinace OSTR?IL Marek
I probably could do it for each row in cycle (the data frame is not big) but I
wonder if somebody knows any more elegant/easy/effective solution for such task.

Hi Petr,
maybe
library("splitstackshape")
cSplit(evid, "V4", "#", direction = "long")
or
library("tidyr")
separate_rows(evid, V4, sep = "#")
is helpful.
Best,
Ulrik
