Bug in bootstrap() (partial matching)

[fweber144]

Partial matching requires to rename argument b of the internal bootstrap() function because it partially matches argument baseline:

options(mc.cores = parallel::detectCores(logical = FALSE))
data("df_gaussian", package = "projpred")
df_gaussian <- df_gaussian[1:41, ]
dat <- data.frame(y = df_gaussian$y, df_gaussian$x)
library(rstanarm)
rfit <- stan_glm(y ~ X1 + X2 + X3 + X4 + X5,
                 data = dat,
                 seed = 1140350788)

library(projpred)
vs <- varsel(rfit,
             nclusters = 3,
             nclusters_pred = 5,
             nterms_max = 1,
             seed = 46782345)
smmry <- summary(vs, stats = "rmse", b = 1, seed = 1234)

gives

Error in .validate_baseline(object$refmodel, baseline, deltas) : 
  Argument 'baseline' must be either 'ref' or 'best'.

Tested with projpred v2.1.1 (from CRAN).
