Extract population details from RAMAS Metapop .mp files.
1  meta(mp)

mp 
A character string containing the path to a RAMAS Metapop .mp file containing simulation results. Metapop .mp files are plain text files that store settings describing RAMAS metapopulation models, and the results of simulating population dynamics according to those models. 
A data.frame
containing one row per population, with columns:
popName 
The name of the population. 
xMetapop, yMetapop 
The spatial
coordinates of the population centroid, in RAMAS's coordinate system (see

initN 
The initial abundance. 
ddType 
The density dependence type. 
Rmax 
The maximum growth rate. 
K 
The initial carrying capacity. 
Ksd 
The standard deviation in K, if applicable. 
allee 
The allee parameter, if applicable. 
kch 
A constant, or reference to a .kch file describing temporal change in K. 
ddDispSourcePopN 
The parameter indicating the effect of source population abundance on its dispersal rate. 
cat1LocalMulti 
The local multiplier for probablity of Catastrophe 1, if applicable. 
cat1LocalProb 
The local probability of Catastrophe 1, if applicable. 
includeInTotal 
Indicates whether abundance of this population is included in totals reported in simulation results. 
stageMatrix 
The name of the stage matrix in use by the population. 
relFec 
The mean fecundity of this population, relative to those given in the stage matrix. 
relSurv 
The mean survival rates of this population, relative to those given in the stage matrix. 
localThr 
The abundance threshold below which the population might be considered dead (depending on global options specified elsewhere). 
cat2LocalMulti 
The local multiplier for probability of Catastrophe 2, if applicable. 
cat2LocalProb 
The local probablity of Catastrophe 2, if applicable. 
sdMatrix 
The name of the standard deviation matrix in use. 
ddDispTargetPopK 
The target population K below which dispersal out of this population is reduced. 
tSinceCat1 
The number of time steps since this population last experienced Catastrophe 1. 
tSinceCat2 
The number of time steps since this population last experienced Catastrophe 2. 
relDisp 
Dispersal rates of this population relative to those specified by the global dispersal matrix/function. 
relVarFec 
Variation in fecundity rates of this population, relative to those given in the standard deviation matrix. 
relVarSurv 
Variation in survival rates of this population, relative to those given in the standard deviation matrix. 
mptools
has been tested with outputs generated by RAMAS Metapop
version 5, and may produce unexpected results for other versions. A warning
is issued if the user attempts to access files originating from other
versions of RAMAS Metapop.
