Question on matrix calculation
Hello again,
Ley say I have 1 matrix and 1 data frame:
> mat <- matrix(1:15, 5)
> match_df <- data.frame(Seq = 1:5, criteria = sample(letters[1:5], 5, replace = T))
> mat
[,1] [,2] [,3]
[1,] 1 6 11
[2,] 2 7 12
[3,] 3 8 13

...ormul", "nanoparticl", "size abras particl", "agent malic acid"))
chemical_df <- data.frame(chemical=c("basic", "alkalin", "alkali", "acid", " ph ", "hss"))
Here is my match code:
library(magrittr)
match_df <- NULL
for (i in 1:length(chemical_df$chemical)) {
match_df<-data.frame(category=concept_df[grep(chemical_df$chemical[i], concept_df$concept), ] ) %>%
rbind(match_df)
}
But I don't want this result:

plyr: version 1.5
...ups.google.com/group/manipulatr.
Version 1.5
------------------------------------------------------------------------------
NEW FEATURES
* new `strip_splits` function removes splitting variables from the data frames
returned by `ddply`.
* `rename` moved in from reshape, and rewritten.
* new `match_df` function makes it easy to subset a data frame to only contain
values matching another data frame. Inspired by
http://stackoverflow.com/questions/4693849.
BUG FIXES
* `**ply` now works when passed a list of functions
* `*dply` now correctly names output even when some output combinations are...
