Unused arguments at function R - r

I'm new in R.
Trying to use the rtriangle function.
swimmerToTornado <- trajectory("to tornado")%>%
log_("Going down TORNADO") %>%
addService(sname = "Tornado", timeDist = function() rtriangle( min = 0.1, max = 0.5, mode = 0.5) )
But I get this Error -
Error in rtriangle(1, min = 0.1, max = 0.5, mode = 0.5) :
unused arguments (min = 0.1, max = 0.5, mode = 0.5)
I tried to remove the 1 argument - still the same error.

I found the answer.
swimmerToTornado <- trajectory("to tornado")%>%
log_("Going down TORNADO") %>%
addService(sname = "Tornado", timeDist = function() rtriangle( 1,0.1, 0.5, 0.5))
Or just like the comment above by #jogo, doing a= , b=, c= will work too.

Network analysis in R: error using findGraph function in qgraph package

I can't get the findGraph function in the qgraph package to work.
The code I'm using is:
optGraph <- findGraph(dataCors, nrow(data), type = "pcor")
optimalGraph <- qgraph(optGraph, layout = corGraph$layout,
groups = Groups, legend.cex = 0.3,
cut = 0.1, maximum = 1, minimum = 0, esize = 20,
vsize = 5)
With the output:
Error in findGraph(dataCors, nrow(data), type = "pcor") : could not find function "findGraph"
I have downloaded all the recommended packages.

How to use lessR functions without load package?

I have a data:
df_1 <- data.frame(
x = c("AA", "BB"),
y = c(1, 2)
)
and the following function:
lessR::PieChart(
hole = 0,
x = x, y = y, data = df_1,
values_digits = 1,
values_color = "#020202",
values_size = 1,
color = "black",
lwd = 1.5,
fill = c("orange", "steelblue"),
main = "Percent"
)
The error occurs:
Error in if (theme != getOption("theme")) { : argument is of length zero
I can't use the library or a withr (or similar) functions, as I'm using the golem framework, which doesn't allow loading packages even temporarily.

Error while running WTC (Wavelet Coherence) Codes in R

I am doing Wavelet Analysis in R using Biwavelet. However, I receive the error message:
Error in check.datum(y) :
The step size must be constant (see approx function to interpolate)
When I run the following code:
wtc.AB = wtc(t1, t2, nrands = nrands)
Please share your help here. Complete Code is:
# Import your data
Data <- read.csv("https://dl.dropboxusercontent.com/u/18255955/Tutorials/Commodities.csv")
# Attach your data so that you can access variables directly using their
# names
attach(Data)
# Define two sets of variables with time stamps
t1 = cbind(DATE, ISLX)
t2 = cbind(DATE, GOLD)
# Specify the number of iterations. The more, the better (>1000). For the
# purpose of this tutorial, we just set it = 10
nrands = 10
wtc.AB = wtc(t1, t2, nrands = nrands)
# Plotting a graph
par(oma = c(0, 0, 0, 1), mar = c(5, 4, 5, 5) + 0.1)

Issues using optFederov of AlgDesign package

i have some issues using the package AlgDesign. I want to create a design using the federov exchange algorithm. Unfortunalty, I run into an confusing error:
Error in apply(data[, numericColumn], 2, mean) :
dim(X) must have a positive length
The error occures using different orders of the grid variables
cand.list = expand.grid(x1 = scale(as.data.frame(c(0, 0.1, 0.2, 0.3, 0.4, 0.5)), center = 0.0, scale = 0.5),
x2 = c("PMX", "MOC","OC","OX2","POS","CX","UX"),
x4 = c("Swap","Invert","Memetic 2-opt","Memetic k-opt","Memetic VNS"),
x5 = c("A","B")
)
federovDesign<-optFederov(~x1*x2*x5*x4,data = cand.list,nullify = 1,nRepeats = 40,center=TRUE)
This codes produces the error stated above. If i use the following code, everything work fine.
cand.list = expand.grid(x1 = scale(as.data.frame(c(0, 0.1, 0.2, 0.3, 0.4, 0.5)), center = 0.0, scale = 0.5),
x2 = c("PMX", "MOC","OC","OX2","POS","CX","UX"),
x3 = c(50, 100,150,200),
x4 = c("Swap","Invert","Memetic 2-opt","Memetic k-opt","Memetic VNS"),
x5 = c("A","B")
)
federovDesign<-optFederov(~x1*x2*x5*x4,data = cand.list,nullify = 1,nRepeats = 40,center=TRUE)
I just add another variable. However, the other variables remain unchanged but the error disappears. I observe this strange behavior every time I am using the package. With a little luck I may get it to work, trying different variable orders within my grid, however, I dont understand the underlaying concept.
I looked at the origin code of the function at github https://github.com/jvbraun/AlgDesign/blob/master/R/FederovOpt.R and tried my first cand.list and no error occures:
cand.list = expand.grid(x1 = scale(as.data.frame(c(0, 0.1, 0.2, 0.3, 0.4, 0.5)), center = 0.0, scale = 0.5),
x2 = c("PMX", "MOC","OC","OX2","POS","CX","UX"),
# x3 = c(50, 100,150,200),
x4 = c("Swap","Invert","Memetic 2-opt","Memetic k-opt","Memetic VNS"),
x5 = c("A","B")
)

So whats the matter? What do i miss?
Thank you for your effort. I have found a solution, its a bug:

How can I code a self arrow in my node diagram in R?

The code I found creates a population matrix node diagram. All I want to do is add a self arrow on the final node i.e. one that points to itself. Hope you can help.
library(diagram)
Numgenerations <- 6
DiffMat <- matrix(data = 0, nrow = Numgenerations, ncol = Numgenerations)
AA <- as.data.frame(DiffMat)
AA[[1,5]] <- "f[4]"
AA[[1,6]] <- "f[5]"
#
AA[[2,1]] <- "s[list(0,1)]"
AA[[3,2]] <- "s[list(1,2)]"
AA[[4,3]] <- "s[list(2,3)]"
AA[[5,4]] <- "s[list(3,4)]"
AA[[6,5]] <- "s[list(4,5)]"
#
name <- c(expression(Age[0]), expression(Age[1]), expression(Age[2]),
expression(Age[3]), expression(Age[4]), expression(Age[5]))
#
plotmat(A = AA, pos = 6, curve = 0.7, name = name, lwd = 2,
arr.len = 0.6, arr.width = 0.25, my = -0.2,
box.size = 0.05, arr.type = "triangle", dtext = 0.95,
main = "Age-structured population model")
You can add the arrow this way:
AA[[6,6]] <- "s[list(5,5)]"
Or, if you want it labeled as a self arrow,
AA[[6,6]] <- "self"
I needed to set relsize to slightly less than 1 to prevent the self arrow from being clipped at the right edge.
plotmat(A = AA, pos = 6, curve = 0.7, name = name, lwd = 2,
arr.len = 0.6, arr.width = 0.25, my = -0.2,
box.size = 0.05, arr.type = "triangle", dtext = 0.95,
main = "Age-structured population model",
relsize=0.97)
