How to get an argument dynamically from a list?
...9;C/A', '154/35')
CLIFF <- c('A/C', 'C/C', '15/12')
PAM <- c('A/C', 'C/A', '13/12')
sampleList <- c("BOB", "MARY", "JOHN", "CLIFF", "PAM")
polyList <- c("rs123", "rs124", "rs555")
#make dataframe with data
data.raw <- data.frame(t(do.call(data.frame, lapply(sampleList, get))))
names(data.raw) <- polyList
row.names(data.raw) <- sampleList
I want to get, for example, data.raw$rs124 using polyList.
I tried

creating a dataframe using a list of the variable names
...;C/A', '154/35')
CLIFF <- c('A/C', 'C/C', '15/12')
PAM <- c('A/C', 'C/A', '13/12')
sampleList <- c("BOB", "MARY", "JOHN", "CLIFF", "PAM")
polyList <- c("rs123", "rs124", "rs555")
to create a dataframe with the data I use:
data.raw <- data.frame(BOB, MARY, JOHN, CLIFF, PAM, row.names=polyList)
which works fine, but when there are several hundreds samples... well, you guess my problem.
I'd like to create the dataframe using the list of the...

attributing values to dataframe positions following eval
Hi everybody,
I've been looking around, but can't seem to find the answer.
I get a list of names (which vary, so I never know them in advance), and
transform them into variables, each of which is a dataframe, using
assign:
polyList <- c("rs123", "rs124", "rs555", "rs000")
numPoly <- length(polyList)
for (k in 1:numPoly) {
assign(polyList[k], data.frame(matrix(NA, ncol=3, nrow=3)))
}
polyList <- lapply(polyList, as.name)
I can see the resulting dataframe associated to rs123 (for example)
using:
&...
