[I am trying to use a sequenced list of depth values as an input in my creation of an array, but it's not working. Keep getting the same error message "negative length vectors not allowed. Help?][1]

Here's the code:

#minimum elevation (ft)
minelev <- 6228
# Maximum elevation (ft)
maxelev <- 6303
# standard sequence of depth values
depthSeq <- seq(minelev, maxelev, 0.1)
# data collected
vars <- c("ODO*", "Temp", "Cond", "Chlorophyll", "BGA", "PC_Chla")
varnames <- c("ODO", "Temp", "Cond", "Chlorophyll", "BGA", "PC_Chla")

Dates <- c()
Locations <- c()
for (i in 1:length(interpfiles)) {
  strg <- unlist(strsplit(
    x = interpfiles[i],
    split = ".",
    fixed = T
  ))
  Dates[i] <- paste(strg[2], strg[3], strg[4], sep = "/")
  Locations[i] <- strg[1]
} #ends for loop 

#simpler attempt for creating empty arrays for each site location before adding columns of additional interpolated data 
row.names<-c() 
col.names<-c("Depth", Dates)
mat.names<-c(varnames)
Gates.array<-array(NA, dim = c(depthSeq,229,6), dimnames = list(NULL,col.names,varnames))

  • Please take a look at how to make a [great reproducible example](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example). For example: `interpfiles` isn't defined. – Martin Gal Jul 20 '21 at 21:25
